Yes, I understand how your program works. What I do not understand is how
you got it. My program came out in IDLE as you see it. No ..., different
indentation, an error message before I could add the else alternative.
(Which, as a Pythonista, one should know, is "Wink-wink".)
In IDLE in the window with the ">>>" prompt:
After the colon at the 'if' line, you press ENTER (ie you tell Python 'the
line has ended here').
The interpreter then supplies the "..." to denote that you are entering a
multi-line statement.
No, IDLE does not supply the ..., that is the source of the confusion.
If you use the interpreter directly from a command/terminal window it
will supply the ... continuation prompt but the IDLE shell will not.
Thank you Kent, I didn't know that.
The story stays the same, except that you don't get the "... " from Python.
That means that the second line and further are all shifted 4 positions to the
left, so you'd need to enter something like:
>>> i = 5
>>> j = 7
>>> if i <= j:
print 'nudge', 'nudge'
else:
print 'whatever'
I agree that this is highly confusing.
The best solution is probably to use the editor window instead, and save/run
your programs from there.
Sincerely,
Albert
