Here the script file, test0.py:
--------------------------
password = 'bad'
if password == 'bad':
print('bad password')
exit()
else:
print('good password')
print('something else to do')
--------------------
When running it under Python3.4 Windows Vista, no problem at all.
D:\Works\Python>py test0.py
bad password
But if debug it under pdb:
D:\Works\Python>py -m pdb test0.py
> d:\works\python\test0.py(1)<module>()
-> password = 'bad'
(Pdb) tbreak 3
Breakpoint 1 at d:\works\python\test0.py:3
(Pdb) cont
Deleted breakpoint 1 at d:\works\python\test0.py:3
> d:\works\python\test0.py(3)<module>()
-> print('bad password')
(Pdb) cont
bad password
The program exited via sys.exit(). Exit status: None
> d:\works\python\test0.py(1)<module>()
-> password = 'bad'
