Re: Moving away from BGT and learning python
Re: Moving away from BGT and learning python Another term for it is namespace, any variables declared in a function stay in a function, unless explicitly returned to the caller to prevent conflicts with other variables outside the given space. Other than using globals, what you can also do is set it up so X is filled with a returned value the function gives back that updates it with a new value, for example:def my_fun(a): a = a + 1 x = a print(a) print(x) return x x = 3 x = my_fun(x) print xKeep in mind that if you use a return call in a function, the function will end and anything beyond the return call will be ignored, so be sure to put it at the end or in places where you want the function to end.

Re: Moving away from BGT and learning python
Re: Moving away from BGT and learning python In Python, when you run the "my_fun" function, the variables are createdinside the function.When the function returns or when it ends, Python removes thevariables that are inside the function and restores thevariables that are declared outside it.This is called a namescope (the function has a namescope which theirvariables are declared, and the script has another).When you tipe x in the interpreter, you are referencing the x of thescript namescope because the function has already ended.Edit: to modify a variable inside a function, declare it as global so itcan be seen on the script namescope. See the example:>>> def set_x_and_print_it():... global x... x = 3... print(x)...>>> set_x_and_print_it()3>>> x3 URL: http://forum.audiogames.net/viewtopic.php?pid=358426#p358426 -- Audiogames-reflector mailing list Audiogames-reflector@sabahattin-gucukoglu.com https://sabahattin-gucukoglu.com/cgi-bin/mailman/listinfo/audiogames-reflector

Re: Moving away from BGT and learning python
Re: Moving away from BGT and learning python so, consider the following code: Note: indentation is a greater than sign:def my_fun(a):>a = a + 1>x = a>print(a)>print(x)x = 3my_fun(x)So I now have a question. If you run this, you will be printed a value of 4 4. Now, here's the fun part. If you type in x in the interpreter it will say, clearly, 3, but wait. I had a statement in the my_fun function that should have set x to 4, so why is it 3? Ferther more, if you type in a, the following will appear:Traceback (most recent call last): File "", line 1, in NameError: name 'a' is not defined but but but... I clearly set a to 4! So why, why in the world does the stupid thing reset and acts as though I have never defined a variable called a? After all, I did do it. So my question is how? How can I change the variable outside of a function instead of declaring a variable that lasts only till a function finishes running? Is it something to do with the return statement? I'd be really grateful for any help and would also appreciate if you provided a code snippid or some such.

Re: Moving away from BGT and learning python Assuming your using IDLE that comes with python, the default configuration opens the python shell interpreter.

Re: Moving away from BGT and learning python
I am using a book called how to think like a computer scientist found at the following linkhttp://openbookproject.net/thinkcs/python/english3e/If you go to chapter 3, you'll see that the book suggests you to enhance the turtle program by allowing the user to set the title of the window and such. Trouble is, the input statement doesn't work. I'll post the code below, or at least the important part. import turtlewn = turtle.Screentitle = input("enter something")wn.title(title)If I run this, it would make the title thewn.title(title)Line instead of asking for input. I tried getting input before initializing the screen but, no luck.

Re: Moving away from BGT and learning python When you start something like an if, while, class, or function, Python expects an indented block to follow.

Re: Moving away from BGT and learning python
Re: Moving away from BGT and learning python You basically use triple quotes or triple ticks when you want to write multiline strings. This does not mean that string needs to be necessarily multiline, but writing single-line strings in tripple quotes makes no sense, although it's not an error.Of course, instead of using multiline strings, you can just use escape sequences such as \n or \r, but it makes things less readable for code writer. For example:"I'm a good boy.\nI'm the best guy in school.\nMy friends really like me."Compare with this:"""I'm a good boy.I'm the best guy in school.My friends really like me."""You see, the second version as multiline string is much more readable.

Re: Moving away from BGT and learning python True. What makes .NET so nice is that you can mix managed and unmanaged code. Also, about pointers, pointers in C++ are not as scary as some people make them out to be. In fact, they're very easy to work with. You usually never have to do manual pointer cleanup because C++ usually handles that for you either upon program exit or upon scope exit. And with C++11, 14 and 17's new STL components, you now have std::smart_ptr and std::shared_ptr to use too, which both free themselves when no longer used.

Re: Moving away from BGT and learning python
Re: Moving away from BGT and learning python You can get an equivalent to NPEs in Python, can't you? I mean, doesn't the exact same principal apply to trying to call a.f() if a is null or if a is None?Basically, you can't expect that a function or method will never be called with invalid arguments, so the very first thing you should do is to confirm that the arguments are valid. A simple "if a is None : return False", or whatever the appropriate default is, or throwing an error, works well enough in most cases I encounter Is it a style thing? Java has ludicrous style conventions, like making absolutely everything into classes, making new classes for extremely specific exceptions, overly verbose class names, package conventions that amount to a lot of wasted space... But those are just style conventions, and unless you're working with a package that has already gone too far down that rabit hole to be salvageable, you can basically treat Java like most C-style languages, just without a global context, right?I basically gave up on Java when BGT and Python proved all around better for my purposes, so if some updates in the past 5 or so years have enforced the tedious clutter, then I missed it.

Re: Moving away from BGT and learning python
Re: Moving away from BGT and learning python @Hrvoje, most of the issues you pointed out, like null pointer exceptions, can be gotten around easily. For example, in C++, you'd either use a library that *doesn't* use NULL or nullptr, or you'd do checks for them.

Re: Moving away from BGT and learning python
Re: Moving away from BGT and learning python Well, honestly. Python's indentation is may be the only thing that may frustrate beginner users. However, Python is a piece of heaven comparing to some other languages where you get frustrated with null pointer exceptions, data conversions, not to mention that it's quite easy to forget to enclose braces when you have lots of nested blocks. I'm using Java at work, and I've realised how I miss Python, although I'm still using it for writing NVDA addons and some other private stuff. Python is far from perfect, because nothing in this world is perfect, but Python is very popular and saves your time a lot, at least from my experience. For me it's more important to get things done as soon as possible, than spending weeks of work on something that I can get in a single day. Life is too short for that.

Re: Moving away from BGT and learning python
Re: Moving away from BGT and learning python
I'm currently writing a large application and have written everything in notepad. I haven't used an IDE at all, unless you count the VC++ command-line developer tools as an 'IDE'. Also, the smart string concatenation that people are referring to is either of the following, if I'm following your wavelengths:1. Printf-style formatting, i.e.:printf ("%s %.3f\n", "Pi is equal to", 3.14159); // prints pi is equal to 3.141.2. Boost.format-style syntax:#include #include std::string s2 = boost::str(boost::format::format("%2% %1%") % 36 % 77 );(Taken from http://www.boost.org/doc/libs/1_66_0/li … rmat.html; lots more examples there.)(I admit, this method is a bit more clunky.)There is, of course, the optional third way of doing things:3. IOStreams-style formatting (setf/setw). Example at http://en.cppreference.com/w/cpp/io/ios_base/setfThere are probably a lot more ways of string concatenation. One other way is through stringstreams:#include using namespace std;stringstream ss;ss << data;ss << data << data << ...;// Repeat until you've got all your data in the stringstream Or you can make a set of <// ss << data << data << ... << data;// Get final stringstring data = "">

Re: Moving away from BGT and learning python
Re: Moving away from BGT and learning python Yeah. I find that, while IDEs reduce some of the work, they make up for it with clutter and navigation and gah just let me write the code in a text editor, read the compilation results, and test the thing.

Re: Moving away from BGT and learning python
Re: Moving away from BGT and learning python Yeah, I was mainly talking about the conditional stuff like switch case statements and the ternary operator. Python's constant if/elif/else blocks feel repetative to type. In C/C++ (Which admittedly is beginning to put this language back in my good graces over Java) is the preprocessor which allows for macros and that sort of thing. Plus, more as a personal preference, I prefer the braces to the forced tabbing system. In C/C++/Java, if I forget a tab somewhere, the compiler and or program is not going to yell at me about it. Not to say anyone that I might be working with on a project won't mind you, but I'd rather have them angry at me when it would be a simple correction requiring little trouble of retesting stuff. I can write the program as I wish and if it works, I know it isn't a blocking issue because I forgot a tab somewhere. If it's a nice enough IDE, a lot of the brace stuff is handled for me as well.

Re: Moving away from BGT and learning python Hi,At post number 7,, excuse me please, but what kind of c/c++ syntax are you talking about? I know some c++ and what I've always seen that a c++ programmer is always bigger compared to a python program. And python is so simple too. To support this, look some python below.a=5b=10a,b=b,awhat the above code did is that it swapped the values those two variables, a and b contained. Imagine doing this in c/c++ or BGT. To do this you will need a third variable.Regards,Amit URL: http://forum.audiogames.net/viewtopic.php?pid=352689#p352689 ___ Audiogames-reflector mailing list Audiogames-reflector@sabahattin-gucukoglu.com https://sabahattin-gucukoglu.com/cgi-bin/mailman/listinfo/audiogames-reflector

Re: Moving away from BGT and learning python
Re: Moving away from BGT and learning python Oh. Thank goodness. I'm getting really tired of BGT and my antivirus having a civil war on my computer, so hopefully seeing more developers migrating away from it might solve most of those issues. Probably not all of them because antivirus software is...well...odd, but still. I'd also add don't neglect the documentation on the website, and poking around Stack Overflow and google.

Re: Moving away from BGT and learning python
Re: Moving away from BGT and learning python Python is a good choice because it's syntax is even easier than BGT. Everything is an object and everything is dynamic, so it's not required to declare data types.When I've started learning Python, which was somewhere in late 2009., I found a book called "A byte of Python". That introduced me to the Python world. Later on if you wish to expand your Python knowledge, read the book called "Dive into Python".My suggestion is go with Python 3, it's the future. Python2 has unicode issues that I faced many times while developing software with Python, and you will sooner or later have to deal with these issues. Python3 is unicode by default, which is something to expect from a programming language nowadays, since almost nobody now is using Windows 9X or ME where ANSI was a standard.You can use wxPython for making GUIs. Sighted developers on the Internet constantly recommend PyQT saying that it's the best, and may be it really is, however it has accessibility issues. BTW, I don't like to use the term The Best too much, .For communicating with screen readers, you have two options, the one is called Tolk and another one is called Accessible Output. However, the repository where accessible output is hosted seams to be currently down, so Tolk is the only good option right now. I'm combining Tolk with Pyttsx3, which is another python library for SAPI support.For 3D audio, you can use libaudioverse. For making games you have Pygame or Pyglet as a choice.For networking, you can use Twisted.And, for converting your Python script into executable, you have Py2Exe, CXFreeze or PyInstaller. I like PyInstaller, because generating exe is simple as writing pyinstaller with additional commandline options. I was using Py2Exe before, but it wasn't updated since 2014.And, most of Python libraries can be easily installed, updated or removed by using pip on command line e.g., pip install wxpython, pip install libaudioverse, pip install pygame, pip install pyinstaller.

First get python 2.7 from python.org don't use python 3 it's syntax is a little and I think it would get a little confusing for a beginner like yourself.I would start out by reading the python documentation it's not great but it will tell you what you need to know. Also read learn python the hard way, there is a version you can buy but the free version is just as good read it and do all the exercises. Read this with the python documentation read together you will learn a lot. Do all the exercises even if they seem to easy for you there good practice.I wouldn't worry about soud libraries right now but there are a few pysonic and there's another one pylama or something like that it's slipped my mind.I would start out making guess the number and small text games. Guess the number is simple enough using random.rand.int and ra w_input.If you have any other questions just ask but like I said the python documentation and learn python the hard way should answer most of your questions.Hth.

Re: Learning Python Thanks, that clears up a lot for me. I had another question though, when naming variables or functions I see that most people seem to use underlines, I heard that you can also use another method where you capitalize the first letter of each word. Is there any particular standard or reason why most people use underlines? I kind of prefer using capitals because it is less confusing when Jaws reads a line of code.

Re: Learning Python
Re: Learning Python
Hello,I tend to write my main function at the bottom of the module just because it allows me to easily jump from the bottom line where I execute the main function to the main function. There is no need to declare a function in any order as long as you are running the function at the bottom of the module. For example:def function1(): print("Hello")def function22(): function1() function3()def function3(): print(" world")function2()I write using python 2 syntax. There are some tendencies that one can do that make python 2 and 3 compatible and this is what I try to do when ever I can. For example:print("Hello world")could also be written as:print "Hello world"but why do it like that? It is unclear and not compatible. print("Hello world") works on both 2.7 and 3.* and it tells us that print is a function... T
here are also some more advantages to treating print as a function. There are keyword arguments that one can use in print the function and not print the statement as well.The only real difference is the input vs raw_input function. Other than that python 2 and python 3 are the same to newbies.If you follow python3 for imports:from .mymodule import myfunctionit works in both 2 and 3.

Re: Learning Python
Re: Learning Python @TJ.BreitenfeldtIt's important to take some previous notes about how your program will work once finished before starting. If you don't, you will rewrite and rewrite code again. Example:1. There will be a main menu.2. THis menu will contain elements.3. You can select each element and then something happens.It could feel ridiculous, but if you didn't,... Example:Oh, I have 4 different kinds of menus, each has its own features, but now I'd like to log all the activity, so... let's code our menus again.Wait, I have implemented the logging feature, but now each menu element returns a string that is added to the log, and I'd like to make my program easy translatable, so I need that each element returns an integer that then is converted to a string according to the choosen language... Let's rewrite all again! Etc.There are a lot of ways to organize your code, depending on your needs. A basic understanding of some of the most common design paterns would help you too. Take a look at the infamous Gang of Four book (GoF), or google for gang of four paterns:http://www.gofpatterns.com/design-patte … nefits.phpBasically, a patern is an organization model for your code that works with any programing language. For example, the observer paterns (also known as event driven patern) implements a messaging sistem whitch allows you objects, functions or whatever, sending messages to other members, such like: hey there! I'm X and someone has just killed me. Or: hey, server, an user instance has send a message to chatroom X... But it's being a boring and long post, time to leave.Hope this helps.

Re: Learning Python When writing code like what frastlin posted above using so many functions, it seems that you have to work backwards starting near the end of the code and writing upwards. Is this the case, or do most people just learn to plan out the program completely first, and have the ability to think backwards.

Re: Learning Python Thanks guys this helped a lot. I have not gotten to using classses yet, but I do see how that would work. I forgot about the return statement to return a value and then use it else where in the program. I was not intending to create a variable called True, I just wanted a simple generic way of creating a endless loop that I could terminate with conditionals. I thought that you could define the Boolean value True and set it equal to the Boolean value of True to get the endless loop. I don't think I actually created a variable there, I believe both values of True are Boolean values.

Learning Python
Hi, I am working my way through the python tutorial "Learn Python the Hard Way." I have made it up to while loops and I thought I would try and create a simple dice roll game. The game has a player 1 and player 2, and uses two dice. The first to 100 wins. I reasoned out one way to create the dice roll, but I was wondering how would you go about creating a dice roll and get the same result as this by using functions. I know that it is better practice to organize your code by using functions. Every time I try to write this program using functions though, I run into a issue where I need to call a variable from another function, but I have read in multiple places that using global variables is bad practice. So, can someone help me figure out the logic for this? I am using python 3.Here is my code.from random import randrangescore1 = 0;score2 = 0turn = 0;while True == True: dice = [randrange(1, 7), ra
ndrange(1, 7)] print ("Press enter to roll..."); roll = input(); while roll == "": print ("You rolled:"); for i in dice: print (i); turn += 1; break; if (turn % 2 == 0): score2 = score2 + dice[0] + dice[1] else: score1 = score1 + dice[0] + dice[1]; print ("player 1's score is: %d \nPlayers 2 score is: %d" %(score1, score2)); if (score1 >= 100 or score2 >= 100): print ("Congratulations! you won"); break;TJ Breitenfeldt

Re: Learning Python
Re: Learning Python
Hi there,Magurp244 has been faster than me ) He answered while I tried to understand python syntax a bit... His code is much more advanced and object oriented, but for a quick revision of your own code, take a look to the following:from random import randrangedef generateNumbers(): result = [randrange(1, 7), randrange(1, 7)] return resultgoal = 25;score1 = 0;score2 = 0turn = 0;while True == True: dice = generateNumbers() print ("Press enter to roll..."); roll = input(); while roll == "": print ("You rolled:"); for i in dice: print (i); turn += 1; break; if (turn % 2 == 0): score2 = score2 + dice[0] + dice[1] else: score1 = score1 + dice[0] + dice[1]; print("player 1's score is: %d \nPlayers 2 score is: %d" %(score1, score2)); if (score1 >= goal): print ("Congratulations! you won"); break; if (score2 >= goal): print("Sorry, you loose!"); break;It's my first attempt to code in python, using python 3.4, so don't expect much... Oh, and really I don't understand some of those breaks... but it runs Talking about global variables, I cannot fi
gure out why someone prevent you from using global variables. In fact, some variables you used (score, turn...) are global variables. It's specially hard to avoid their use working under a non object oriented paradigm as you did in your example, you will need a place to store and share information sooner or later.

OK, first, that is a little too simple for functions, just use if statements to check it. You need to add something like random turns to make it more reusable. Either that, or add a main menu and whatnot. Here is the basic game, then I will show you when you would use while True:import random

#The next line chooses a random player to start
current_player = random.choice(player_list)
winner = None
print("Welcome to the player dice roler!\n%s is first:" % current_player[0])
while not winner: #What you were looking for is: while True: but frankly you only use that if you don't want the game to ever stop.

winner = current_player

Re: Learning Python Randint return's a single number between x and y. Randrange works very similarly, but you can also configure it to skip sets of numbers. For example, if you write:random.randrange(0,10,2)It will return a random number by two step intervals, such as 0, 2, 4, 6, 8, and 10. If you write:random.randrange(0,100,10)It will return a random number at ten step intervals, such as 0, 10, 20, 30, etc. URL: http://forum.audiogames.net/viewtopic.php?pid=230495#p230495 ___ Audiogames-reflector mailing list Audiogames-reflector@sabahattin-gucukoglu.com https://sabahattin-gucukoglu.com/cgi-bin/mailman/listinfo/audiogames-reflector

Re: Learning Python
When returning things from functions you have to store it in a variable or it will be lost. For example:result = DiceList()This will call Dicelist() which return's dice, its then stored in the result variable for handling. So making that little adjustment it should work fine.from random import randrange

Re: Learning Python
Re: Learning Python you can create a variable named true (lowercase t) and set it to the boolean value of True (capitol t). but as i said, thats not very good practice. for example, if you are making a while loop to loop until a specific number is rolled i might use:target_rolled = False while not target_rolled: #blah blah blah codebut you see. use a variable that pertains to what it is you're doing.

Re: Learning Python
Re: Learning Python the reason people say not to use global variables, is that this one variable is jumping all around to many different scopes of the program and being modified all the way. so if a bug comes up based on that global variable, it probably will be much harder to pin point exactly what is causing that error if it is global vs local. the idea of structuring your coding into classes and the like does help with some of that. also, using the return statement after functions does help as well.i'm not sure if the random module differs between python 2 and 3, but i used random.randint(1,6). might just be about the same thing.fyi, i'd never use true as a variable name. you want to avoid names like that that are already in python, true, false, print, class, and i/j/p. there are probably a few others.

Re: Learning Python HiThanks so much. One more question. Can I use more then one statements with many spaces, like brackets in other languages?

Re: Learning Python
Re: Learning Python Then, Can I define a function, indent it with two spaces, Use the if statement, and Can I just end up just the if statement in the function by decreasing a space?Sorry for my lots of questions.

Re: Learning Python
*Note* you don't need to put ; at the end of your lines.Yes, if you go out an indentation it is like putting a }Here is sudo _javascript_ python using braces to show you what is going on.def my_function(){print("Hello world")}so no return is needed, it does it for you. It automatically does:return Nonewhich is void. As an example:def my_func(blah): if blah.startswith("h"): if blah.endswith("d"): print("Hello world") elif blah.endswith("k"): print("No idea") else: print("Maybe your name?")You can also make a function in a function, but there is very few reasons for it:def func1(): def func2(joe): print(joe) print("Outside the second function's deffinition, but
before the return of function1") return function2function1("My name is frastlin")

Re: Learning Python
Re: Learning Python HiPost 7, I have a question.How to specify the end of the function in python?Other programing languages use brackets or function, end function keyword, but python does not. We define a function using def keyword. And We write the body of the function. And how to specify the end of the function?

Re: Learning Python
Functions in python use indentation, so once you stop indenting python knows that everything else is not in the function. example:function example(): print ("This line is indented four spaces"); print ("All lines in the function must be indented the equal amount of space");print ("this is not apart of the function because it is not indented and against the margin.");

Re: Learning Python
I am not sure if I understand what you mean by "more then one statements"You can stack indentations though. Say you have a function and an if statement inside that function, the code with in an if statement is indented just like a function, but because the function has already indented the if statement you would now have to indent the code for the if statement 8 spaces rather than 4 spaces. That may have been confusing, here is an example.def example(): print ("this is a line inside the function that is indented 4 spaces"); if (5 > 3): print ("5 is greater than 3. This is indented 8 spaces because you have to indent the code for the if statement");print ("this is outside the print statement");you can nest as many statements as you want inside each other like any other language, but you have to keep track of the spacing.

Re: Learning Python Yes, you can use any number of spaces as far as I can tell, however using 4 spaces or the tab key seems to be the standard. I have heard in a couple places not to use tabs, but I think it is just preference. I use tabs because it is much easier to work with and Jaws reads tabs very well in ed sharp (the text editor I use). Also, it is not as time consuming having to press the space bar so many times, and you can still stick with the standard since a tab is equal to 4 spaces. note: I used spaces in my post because it seems to be easier for jaws to identify the indentation since he only reads blank if you are navigating character by character. if you use a screen reader I recommend turning on the setting so that the screen reader will read indents at least just for your preferred tool for editing python code.
