In IDLE, the ">>> " prompt should be ignored when indenting, like this:
>>> if condition:
do_something()
else: # <-- correct, although it looks strange
do_something_else()
If you tried to indent the "else:" to match the "if" like this:
>>> if condition:
do_something()
else:
do_something_else()
or this:
>>> if condition:
do_something()
else:
do_something_else()
you'll get and error because the "if" is actually in column 0
(remember, you should imagine the ">>> " isn't there!) while the
"else:" is in column 4 or 8.
Pressing Backspace before the "else:" should fix the indentation.
Hope this helps.
