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. Notepad + the command prompt is generally sufficient, but Python.exe launches a useful terminal, also.

Re: Moving away from BGT and learning python
Re: Moving away from BGT and learning python Hi Amerikranian.Goodness, I am tired of hearing stupid stuff like this! Yes you can use notepad to write python programs no problem. I've seen this in many python tutorials, "Don't use notepad, it's very bad!" If it's easier for you to use notepad then go ahead. You can still run scripts with the command prompt if you really want to later. Just keep in mind that the books are wrong about things sometimes.Hth.

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,Actually the %s thing is still valid in python 3 as I just checked it out. IF you don't want to use it then you can use the power feature introduced in python, called f strings or formated strings. like this: name="amit"print(f"hi {name{!")As you can see this is much more simpler than that %S or other methods to do this.Regards,Amit

Re: Moving away from BGT and learning python
a= (b) ? c : d; switch (e) {case f : g(); break;case h : i(); break;}And then there are c-style macros.Python is supremely simpler overall, but I do need the terniary operation far more often than swapping.Yeah, Python eventually added its own version (which is annoying to port, since it puts the arguments in a different order), but it's not as quick as a=(b)?c:d; But that's all I can think of that python does less conveniently. ... Well, that and the lack of smart string concatenation.

Re: Moving away from BGT and learning python
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 Hi.Both python 2 and 3 both have pip now, you just need to edit the systems variables. Pip won't respond in command prompt unless you do this.

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. While python is not my favorite language as it lacks several of the nice time saving syntax found in C family languages, I won't deny that it is not too difficult to learn.

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.

Moving away from BGT and learning python Hi there,so very recently I decided to just finally move on and try something new. I want to do other things besides games etc, and I need to learn a better programming language than BGT. So...from a bgt user, what are some tips or resources to learn python. BGT is so simple that its hard to move away from, but it needs to be done. It is clear that it's done and it probably won't ever be updated again.
