A while back I made a big fuss about how IDLE indenting works. Kent was
finally able to use language simple enough for me to understand. So I
kept working IDLE. Today I got an error message. Somebody fixed it! It
now indents just like all the other Python windows. Great going, Snake.
And thank
Allen G.asked me how I made IDLE work. I did nothing on purpose. One can
open Python into the IDLE window or into the program window. I recently
changed from the program window to the IDLE window. IDLE now works
exactly right. As a bonus my DOS-oidle window which used to produce
error messages
At one time I could not run a skit in IDLE nor with the command line.
IDLE gave error messages because (Alan G. says) of the 3 chevrons.
The command opened into a wee square & issued only error messages.
Then the command line opened into a 4x7 box and worked perfectly.
IDLE also now works perfectl

Well, Kent was right, it was an indent error, but 'way high in the
program. I was so catching commas that I got sloppy at an indent
change. sorry guys.

I used to do Basic and enjoyed it. Someone said Python was a vastly
better language than Visual Basic, which I considered playing with. So
I sought to give it a go but struck a sticking point very early.

Hey, guys, forgive me; I can't help being a fool. Just now I READ the
program and it worked perfectly! 42 is more than 1 so it printed
"More". My error was that I imagined there was a loop where no loop
could be. Oh, me; oh, my.

I wrote this two liner. I wanted to save it and then to bring it back
as program.

>>> print brain
life
I saved it as brain.py,

The above text was copied from a window named
"??futz.py-C:\Python26\futz.py" The ?? is two red
script characters which I cannot read. When I go

Shouldn't 'F5' get me a window
Some say that Python programs run better on DOS. I cannot find a way to
do that. I can go 'Python Command Line' to wind up on a black screen
version of IDLE but I can't get from the interactive to executive mode.
Is there any advantage to running .py on DOS?

I keep getting the error message & must re-boot to enable IDLE work. Is
there some rule about 'saving' or about having too many windows open?
It seems to happen if I am doing a lot of saving & re-saving.

I am trying to learn loops. These nested 'whiles' work OK but I would
like to
I recently asked a question about 'for' loops, expecting them to be
similar to 'for-next' loops. I have looked at several on-line tutors but
am still in the dark about what 'for' loops do.
Does anyone have a plain English about the use of 'for' loops?
Are 'while' loops the only way Python runs
and your response was most gratifying. I think that I now have a handle
on the subject and want to say, "Thanks to you all." WM

As a BASIC, hobby programmer, (long since), I get so jargonized here
that I seldom ask about anything any more. The only useful bit I have
gleaned from reading many, many posts is the URL for projecteuler.

will benefit mor
One of the replies to my post explained how difficult it is to address
an audience composed of several levels of skill. I understand that, nor
was I condemning anyone who has a better command of jargon than I have.
Jargon is essential to any trade. What I wanted to do was give Wayne the

I am getting a little dizzy here.
I know about text editor, code, save, F5.
Many tutorials say that it is funner and faster to test an idea
'interactively', using IDLE.

The above is just what the tutorials said would happen.
Can anyone give me a step-by-step in IDLE 2.6 that would make this happen?

I felt such a monkey until Kent convinced me that the 'else' only
appeared to be un-indented.
