Question

I made a program in Idle that says:

for trial in range(3):
if input('Password:') == 'password':
    break
else:
    # didn't find password after 3 attempts
    **I need a stop program here**
print ("Welcome in")

Remember, this is in Idle, so I need program for Idle, not CMD. I also am using Python 3.2, if that helps.

Answer 1

use sys.exit() or raise SystemExit

import sys
for trial in range(3):
    if input('Password:') == 'password':
        break
else:
    sys.exit()
print ("Welcome in"))

Edit:
To end it silently wrap it in a try-except block:

try:
    import sys
    for trial in range(1):
        if raw_input('Password:') == 'password':
            break
    else:
        raise SystemExit #or just sys.exit()
    print ("Welcome in")
except SystemExit:
    pass  #when the program throws SysExit do nothing here,i.e end silently
