It would appear that get items is a generator which uses the token exactly
once when it is first started; subsequent calls to the generator all use
the same token. You need to test the token; if it fails,
obtain a new one, then start the loop.

Re: How to start using python

[Bob Gailer]

I am not feeling well these days. It is sometimes difficult for me to
respond to others the way I would like to.  This is a long reply; in my
humble opinion is important to read all of it

1-whenever you respond to an email from one of us please include the help
list what you can do by reply-all since there are others on this list who
also help.

2 - you did not provide the information I had requested. It's really hard
to help without that information.

3 - problems like you are facing are usually due to some unusual
installation method.

4 - I suspect when you run the Visual Basic icon you enter an interactive
development environment. True? Python also comes with an interactive
development environment its name is IDLE. Idle is normally installed in a
subdirectory how's the one that contains python.exe. once you locate that
director you'll be able to run idle and you will be in an environment that
will look somewhat familiar to you. There are tutorials specifically
written to help you use IDLE. Others on this list can tell you how to
locate that tutorial.

5 - I am sorry you are having such difficulty. It is relatively unusual for
newcomers to experience that.

6 - suggestion: uninstall the thing you installed. go to python.Org. find,
download and run the correct installer paying attention to any information
it gives you on where it is installing python. then try running py again.

Visit www.Python.Org there should be some links to tutorials that should
cover the topics of how to install python and how to start using it. If
that does not help come back to us with more information including your
operating system, the website from which you downloaded the installer, the
name of the installer file, and what you did to install python. You also
might try from a terminal or command prompt typing py, which should start
up a python Interactive session. You should see>>> type 2 + 3 hit enter you
should see a new line displaying five. Let us know how it goes and we'll
give you a hand from there.

Well it's actually a little more involved than that. When python import a
module it executes the module code. This is why you often see at the bottom
of a module:

if __name__ == '__main__':
  # code to execute when running the module as opposed to importing it.

When importing a module __name__ is the module's name rather than
'__main__'.

What happens when module A Imports module B depends on whether or not the
import B statement is actually executed.

We need a lot more information in order to help you. Operating system?
Where did you get the installation file? what does "everything" mean? Show

Re: Getting the dependencies of a function from a library

For me the question is a little vague.

What do you mean by Library?

Could you give us a simple example of the input and the output?

It's possible to interpret your question as an assessment of your skill
level. We know nothing about your skill level.

It's possible to interpret your question as to whether or not this is a

If you succeed in coming up with a sample input and output then how about
trying to write a program to process that input to get that output. Post
those results to this list and we'll see what we can do to help you.

The program you downloaded is an installer. You run an installer one time,
then you find the program that was installed ( python.exe  in this case)
and run that program. Exactly how you run the program depends on the
operating system and where you chose to install the program. See the
documentation at python.org for operating system specifics.

Try this out then get back to us for more help. When responding please

 self.pushButton.setText(_translate("MainWindow", "SCAN"))
 self.label.setText(_translate("MainWindow", "WELCOME"))

 self.pushButton.clicked.connect(self.copy)

When user clicks button self.copy is invoked. True?

 def copy(self, MainWindow):
 self.pushButton.setText('WORKING...')

Why do you sometimes use _translate and not other times?

 self.pushButton.setStyleSheet("background-color: rgb(250, 0, 0);\n"
"color: rgb(255, 255, 255);")
 testprompt=storeid=pyautogui.prompt(text='test', title='test')


This method does no actual work! If you add

self.pushButton.setText(_translate("MainWindow", "SCAN"))
self.pushButton.setStyleSheet # whatever it was originally

it will reset the button. Of course it will so really fast, as there is 
no actual work being done.


So you should first address the issue of actually doing something that 
will take a little time. Also it is not a good idea to duplicate code, 
so I would put those 2 lines in a function and call that function from 2 
places.


Am I going in the right direction? Am I missing something?


class Application():
 def run():
     import sys
 app = QtWidgets.QApplication(sys.argv)
 MainWindow = QtWidgets.QMainWindow()
 ui = Ui_MainWindow()
 ui.setupUi(MainWindow)
 MainWindow.show()
 sys.exit(app.exec_())

Application.run()

You're getting that response because you are re-running the installer
rather than running python.

Take a look at
https://docs.python.org/3/tutorial/interpreter.html#invoking-the-interpreter

There is a section explicitly for Windows.
Whoever asked you to download python has made the incorrect assumption that

First a couple of pointers to help you get the results you want in future
communications.

Use a meaningful subject rather than help. Why? Because we keep track of a
communication thread by the subject. It also helps us decide whether or not
we can even tackle that particular problem.

Send such requests to tu...@python.org.

Understand that urgency on your part does not translate to urgency on our
part. We are volunteers who donate some of our time to giving help.

You can accomplish your objective by using various string processing
functions or by using regular expressions. I will assume that you want to
extract everything between square brackets as the error and everything
following the 2nd quote as the timestamp. Let's use the string find method.
With that you can get the index of a particular character and use string
slicing with those indexes to get the actual strings. If you have a basic
understanding of python that should be enough to get you started. Otherwise
I suggest you start with a tutorial that will get you those basics.

if you just want someone to write the program for you then one of us will
be glad to act as a paid consultant and do that for you.

[issue37430] range is not a built-in function

[bob gailer]

bob gailer  added the comment:

Thanks for explaining. Indeed range appears in __builtins__. It is a surprise 
to type range and get  in response. sum otoh gives . The distinction between function, type and class seems muddy.

When I enter "range" in the index box in the windows documentation display I am 
offered: 

(1)built-in function, which takes me to the paragraph that started this issue. 
It does NOT take me to the built-in functions topic, whereas sum does.

(2) object, and range (built-in class)which take me to the built-in types 
topic. This seems to add to the confusion.

In section 8.3 The for statement there is a reference to range as a built-in

All of these are probably installable using pip. By the way did you mean

Re: OT - need help with PHP

[bob gailer]

Thank you for your various responses.  All helpful and encouraging.

RE mailing list: I followed the instructions at 
http://php.net/manual/en/faq.mailinglist.php.


I have had no response. Shouldn't I get something either welcoming me to 
the list or requesting a confirmation?


Here are the instructions from the api vendor: (somewhat lengthy)

HOW TO CALL A FUNCTION USING VOIP.MS REST/JSON API
The following samples show how to get all Servers Information from our 
database and how to select a specific Server for your display purposes.


Please Note:
- When using our REST/JSON API you need to send the Method to be used 
and the Required Parameters as part of the URL.

- By default the output Content-Type is "text/html".
- If you want the output Content-Type to be "application/json", add the 
following to your URL: _type=json


PHP - Using cURL GET - Sample Code

|$ch = curl_init(); curl_setopt($ch, CURLOPT_RETURNTRANSFER, true ); 
curl_setopt($ch, CURLOPT_URL, 
"https://voip.ms/api/v1/rest.php?api_username=j...@domain.com_password=password=getServersInfo_pop=1;); 
$result1 = curl_exec($ch); curl_close($ch); 
$data1=json_decode($result1,true); print_r($data1);|



PHP - Using cURL POST - Sample Code

|$postfields = array( 'api_username'=>'j...@domain.com', 
'api_password'=>'password', 'method'=>'getServersInfo', 
'server_pop'=>'1'); $ch = curl_init(); curl_setopt($ch, 
CURLOPT_RETURNTRANSFER, true ); curl_setopt($ch, CURLOPT_POST, true ); 
curl_setopt($ch, CURLOPT_POSTFIELDS, $postfields); curl_setopt($ch, 
CURLOPT_URL, "https://voip.ms/api/v1/rest.php;); $result = 
curl_exec($ch); curl_close($ch); $data=json_decode($result,true); 
print_r($data); |


Note: I have edited these examples by removing unnecessary stuff, to 
make their size reasonable.


On the Python side, I can make the GET version work using 
urllib.request. I will try requests soon.


When I try to run the post example using php -r "path-to-php-progran"; 
It just prints the program.


Any attempt at converting that to POST get me a Bad Request response.

One of my needs is to upload a .wav file. The vendor requires the file 
to be encoded into base64  and the result string included in the POST 
data, which can lead to enormously long POST data. I can successfully 
use GET to send very short .wav files, but the url length limit is 
quickly reached for a reasonable length recording. Trying to use the 
POST ability that allows me to specify the file by path fails at the 
vendor side.


Apology for long post, but I don't know what to omit. Again any help is 
welcome.

OT - need help with PHP

[Bob Gailer]

Trying to setup PHP on Windows 10  using the curl extension to run
standalone. Why? I am trying to use an API where the only coding examples
are written in PHP. My goal is to use python, and the place where I'm stuck
is: the examples use Curl to post requests; my attempts to translate this
to urllib. request have failed.

I can't even figure out how to sign up for a PHP email list.

Re: How do I get a python program to work on my phone?

[Bob Gailer]

kivy has a very steep learning curve. The easy way to use kivy is to
install the kivy launcher app which then lets you run a Python program and
access the kivy widgets. If you really want to dive into kivy I will send
you a presentation I gave on kivy. After a lot of work I did manage to
create an install an app.

An interesting alternatives to create a simple web page to run in the
phone's browser. If you don't already have a server on the web you can rent
one from secure dragon for as low as $12 a year. Install websocketd and
python. Websocketd lets you do all sorts of interesting things such as
serve static pages, CGI programs, and use websockets. Websockets requires a
little bit of JavaScript but makes the interaction between a browser page
and a Python program on the server ridiculously easy. Much easier than
Ajax. Feel free to ask for more information. I posted a Python program on
the websocketd website that shows how to do the server side of websockets
communication.

can you help me to fix it?! :\

Suggestion:

Pretend that you are the computer.
Mentally execute each statement, providing input as required, and write
down the results.
Something like:
Statement   Input   Result
13 number1 = 3
22 number2 = 2
31 number3 = 1
4  Max number is  3
5  False
6  Max number is  1
Do not guess or assume anything. Just do exactly what each statement says.

As an alternative use some kind of debugger that will let you step through
the program statement by statement. Most interactive development
environments such as IDLE let you do this.

You might as well learn to do this now as you will be needing it more and
more as you go on.

Personally I would not have given any answer to the problem until you had
an opportunity to research it more thoroughly. We don't learn by being
given answers.

Also in the future use  tu...@python.org  as that's the proper place for
this kind of question.

Why:

What is wrong with:

match = pattern.search(data) is not None

returns True or False, which is then assigned to match. On the other 
hand, in

match is assigned the result of the search; then that is compared to None.

My feedback is:

Firstly there's a blank line between every line of program text which makes

Also some statements are spread out over more than one line which also
makes it hard to read.

Secondly this sounds like a homework assignment. Is that true? If so be

It is actually sufficient to just say print)names) since that works equally
well in 2 or 3.

Re: int.to_bytes() for a single byte

I'm using Python 3.6.  I have a need to convert several small integers into

This seems to work, but I find it cumbersome.  I have to supply the byteorder argument to prevent a 
TypeError.  However, byte order doesn't matter if I'm only generating a single byte.  Whether I 
choose "big" or "little" I should get the same result.  Is there another 
function which provides a more logical interface to this straightforward task?

Take a look at the struct module.

Re: Python Enhancement Proposal for List methods

[Bob Gailer]

Many of the features of python were added not out of need but rather for
convenience.

If need were the only criteria we could immediately get rid of
comprehensions, since they can be written as a series of for loops, the
same can be said for many other newer features.

Python is all about making the programming experience easier and more
productive. Expanding replace  from just strings to other sequences such as
as lists makes sense. The cost in time and effort to add this to python is
trivial.

I say go for it.

It is our policy to not write code at others requests. We are glad to help
if you've started writing a program and are stuck.

Out of curiosity where does this request come from?

If you want to hire one of us to write the program, in other words pay us
for our time and expertise, that's a different matter. We would be happy to
comply.

The only help I can give at this point is to suggest that you tell us what
you tried and how it failed. Please copy and paste any relevant terminal
entries and error messages. No screenshots no attempts to rephrase just the
facts. Once we have those we can take the next step. Just out of curiosity

I suggest you conduct a walk-through. That means pointing using a pencil or

to what happens when the loop repeats.

This will do more for you than if I just tell you the answer.

Since python is a general purpose programming language, I'd say yes. I
would add the use of a database management system, since you need some way
of storing the data. sqlite is an excellent database management system with
an excellent python interface. Unlike other database systems, sqlite is
single-user system. You can always migrate later to a multi-user system.

The sqlite3 module is included in the python distribution.

IBM has had for a very long time a program called Pipelines which runs on
IBM mainframes. It does what you want.

A number of attempts have been made to create cross-platform versions of
this marvelous program.

Re: detaching comprehensions

   Maybe you all know this, but to me this is something new.
   I learnt it by trial and error in the Python 3.6.0 console.

   Most will know list comprehensions:

|[3, 4]

   I found out that the comprehension can be detached from the list:

|>>> k =( i for i in range( 3, 5 ))

   but one must use an extra pair of parentheses around it in the
   assignment.

   Now I can insert the "generator" »k« into a function call,
   but a spread operator should cannot be used there.

|>>> sum( k )
|7

   »sum« expects exactly two arguments, and this is what »k«
   provides.

Where did you get that idea. If you look at the docs you will see:

"sum(iterable[, start])
Sums start and the items of an iterable from left to right and returns 
the total. start defaults to 0."


sum expects 1 or 2 arguments; when you write sum(k) you are providing 1 
argument.


   But to insert it again into the place where it was "taken
   from", a spread operator is required!

|>>> k =( i for i in range( 3, 5 ))
|>>> [ *k ]
|[3, 4]

"taken from"??
k is a generator object.

Help on built-in function floor in module math:

 Return the floor of x as an Integral.
 This is the largest integer <= x.

   Is the output of »help(floor)« supposed to be a kind of

   Is there any hint in the documentation about the type

IMHO its a good idea to introduce conversational programming early. Start
with input() and print() then int(), if, while, break . Add one item at a
time.  This will be more interesting and useful than a bunch of data types
and operators, and  answer a lot of questions that otherwise show up on the
help and tutor lists. Also explain tracebacks. None of the above in great
detail; just let students know there is more detail to come later

We are here to help but we don't have crystal balls to interpret your

The best thing you can do is show us what attempts you have made to write
code for this problem and the difficulties you have encountered.

We always assume when given a problem like this that it's a homework
assignment. So it's a good idea to state that upfront.

Have you had any success in writing and running any python programs?
Assuming that you are in a class, what aspects of python have you already
learned? Can you apply any of that to this problem? The more you give us
the easier it is for us to help.

Sending this to docs in hopes of improving documentation of % formatting

I get what it's doing, it just doesn't make much sense to me.  Looking at 
operator precedence, I only see the % operator in regards to modulus.  Nothing 
in regards to string formatting.  Is it just a side effect of the % being 
overloaded in strings?   Or is it intentional that it's higher precedence...and 
why?
The documentation is unfortunately flawed. If you look at the .chm file 
in the docs folder under the python installation 
(c:\python35\docs\python351.chm as an example, and enter % in the index, 
you will see:

%
  operator
% formatting
% interpolation
note that modulo is missing!

double-click operator to see the numeric operator
double-click % formatting to see the string "unique built-in operation" 
aka interpolation.

See under section 6:16 Operator precedence:
  "[5] The % operator is also used for string formatting; the same 
precedence applies."


Maybe I'm making too big a deal of it.  It just doesn't 'feel' right to me.

Unfortunately "feel" is not a good guide to understanding programming 
languages.

COBOL and Assembler use MOVE when it is actually COPY!

Slight OT digression: The language that is best for me is APL in which 
there is no operator precedence to worry about. Execution is strictly 
right-to-left. () are used when the order of evaluation needs to be 
altered. I recall one person telling me that "right-to-left" was not 
natural. He preferred "left-to-right" as in FORTRAN. So I considered the 
FORTRAN statement A = B + C * D. Turns out that A * B happens first, 
then C + then A =. Sure looks right-to-left to me!

We can assume you are at a Windows command prompt. It' a good idea too tell
us that,  so we don't have to assume!

and open a command prompt with "python" and get the prompt.

Assumptions / terminology again! Typing "python" normally invokes the
python interpreter. Since you did not pass any arguments you get a window
displaying the python interpreter prompt (>>>).

It is great (as John said) that you provided the traceback. It would have
been even greater if you had given us the rest e.g,

Type "help", "copyright", "credits" or "license" for more information.
>>> python comment.py

Which brings up one other important matter: when writing us also tell us

Huh? The character sets I'm familiar with don't have "word separators".
Space is just another no -control character.

Editors allow your choice of font. Some are proportional, some monospaced.

Hi,

The book is written for beginners of python programming language and written in 
learn-by-doing manner. If some group members can review the same, it will be 
useful for myself to come up with an improved version.

Who is the publisher of this book?

I just took a look at the pages that can be viewed on Amazon. Many 
reactions. it is hard for me to write this, as it seems it would sound 
harsh, judgemental, unappreciative. But you did ask for a review, and 
this is my honest reaction.


I find it hard to read a book written by a non-native speaker of 
English. I an constantly having to overlook what to me are spelling, 
grammatical and vocabulary errors. I HIGHLY recommend you find an editor 
who can fix these errors.


When I pick up an "Introduction to ." book I expect to get right 
into the language. History, interpreted vs compiled, examples in C, if 
included at all should go in an appendix.


I think you should be teaching Python 3 rather than 2. I disagree with 
your reasons for sticking with ver 2.
I, as a developer using Python for over 10 years, welcomed ver 3 and now 
use it exclusively.


Last sentence of 2.2 is confusing.

Section 2.3 you need to tell reader how to obtain a python prompt. The 
example is also confusing, since to most python users it looks like:

>>> 2+4
6

The result of 2+4. does not appear.

sudo apt-get won't work on Windows. Tell the reader that this is how to 
do it in Unix, and show the Windows equivalent.


I would avoid showing from xxx import * as it is likely to cause 
confusion when a module so imported overwrites a built-in.


Bottom of p 23 (sys.sizeof(). How would a python newbie know to import sys?

I will stop here - there are many other issues.

I am, by degree, an engineer. If this were my introduction to python I 
probably would walk away from python, discouraged by how hard it is to 
learn.

When you call a function from within that function you are using recursion.
This is not what recursion is intended for. If you play long enough you
will run out of memory.

The proper way to handle this is to put the entire body of game() in a
while loop.

Since the values of e and f are not changed in the loop he will continue to
get the same thing.

Not without seeing the code for matchdetails_init. Likely we'd also need to

The comprehension collects the values of the 10 calls to print(). print()

Even without knowing the operator precedence, this will be evaluated either
as:
(name == "John Cleese") or "Michael Palin")
or:
name == ("John Cleese" or "Michael Palin").

Case 1: (name == "John Cleese")  evaluates to either True or False. False
or "Michael Palin" evaluates to  ( believe it or not) " Michael Palin"!
Which, as far as if is concerned, is True. True or "Michael Palin"
evaluates to True.

Case 2: "John Cleese" or "Michael Palin" evaluates to False; name== False
evaluates to False.

One way to get the results you want:
if name in ("John Cleese" or "Michael Palin"):

In the mid 1970' s I helped maintain an installation of IBM' s APL
interpreter at Boeing Computer Services. APL uses its own special character
set, making code unambiguous and terse. It used a left-arrow for
assignment, which was treated as just another operator. I will always miss
"embedded assignment".

A year later I worked on a project that ran on a CDC 6600? where only
FORTRAN was available. The program's job was to apply user's commands to
manage a file system. FORTRAN was not the best language for that task, so I
designed my own language, and wrote an interpreter for it in FORTRAN. In
retrospect a very good decision. That program was in use for 10 years!

Yes. Caveat : python Boolean operators return the value of the last
argument necessary to determine the outcome.
Example :
2 or 3 results in 2
2 and 3 results in 3.
0 and 3 results in 0.
