Hi and please help me understand if it is a bug, or..,as someone said,
there's a 'bug' in my understanding:
(Python 3.2 (r32:88445, Feb 20 2011, 21:29:02) [MSC v.1500 32 bit
(Intel)] on win32) (windows vista, the regular windows python installer)
It's about the following code:
while True:
s =input('Enter something : ')
if s =='quit':
break
print('Length of the string is',len(s))
print('Done')
when I put it in a editor, and run it from there ("Run module F5"),
it runs fine; but when I try to type it in the python shell (IDLE), or in the
python command line, it gives errors, though I tried to edit it differently:
>>> while True:
s = input('Enter something : ')
if s == 'quit':
break
print('Length of the string is', len(s))
print('Done')
SyntaxError: invalid syntax
Tabs do not survive in email/newsgroup posts. Bad idea to send.
In any case, the interactive interpreter and IDLE shell imitation
thereof only parse one (1) statement at a time. You are trying to type
two be removing the indent. When interpreted as one statement, the
dedent is an error. However, above was wrong in original anyway.
>>> while True:
s = input('Enter something : ')
if s == 'quit':
break
print('Length of the string is', len(s))
Up to here, this version was correct, just hit return twice to run.
But I almost never type something so complex in the shell. I nearly
always use editor, where I can correct mistakes easily.
