Re: PyPad 2.7.1 (Update 2)

[Bill Allen]

Jon,

Looks very promising.  Seems to be an issue with interactive mode.  The
following code behaves as thus:

testvar=raw_input("enter value: ")
print testvar


When run, the prompt from raw_input does print to the output screen as:
enter value:


But when you tap in the lower window to enter the value for the input, the
app closes unexpected.  When I reopen it, what I was working on is still
present.

However, if I tap into the lower window and do this one line at a time from
the interactive prompt >>>, the above code works ok.

A problem?   Or am I missing something?

Anyway, I love this little Python app.   Been wanting something like this
for a long time.  I installed this on my iPhone running iOS 4.3.3 (8J2).

Congrats on a great app!

Bill Allen

Re: Abandoning Python

[Bill Allen]

You have ideas, a text editor, and a computer - best get to coding.   What's
stopping you?  You largely want Python, with modifications.   Join the
development team and help implement those changes, or fork your own flavor
and do what you wish.   Right?  You imagine it's an easy task, so get after
it.   Also, quit saying "give me".   I realize that was a troll post, but I
hear people say so many things like this about lots of things.   Sick of
it.  Shut up and do something constructive instead.   Contribute with
effort, rather than a lot of "wishlist" and "give me" talk.

Re: Python's equivalent to Main calling program and subprograms

[Bill Allen]

Thanks for the explanation of "main".   Some tutorials mention it, some
don't.   I have written some not trial Python programs and have never had a
real need to use that convention, but at least I understand it now.

Re: Python on wikipedia

[Bill Allen]

Yeah, I noticed that a while back too.   Kinda cool.

Re: Which is the best book to learn python

[Bill Allen]

Alan Gauld has written a very good online book called Learning to Program.
I would definitely recommend it.
