I am back to being confused. I just tried running the module without
first importing it, and it worked just fine. How do I do this properly
to where the module only runs if I import it?
Code:
def MultiplyText(text, multiplier):
'''Recieve a S & int. For digits in S, multiply by multiplier and
return updated S.'''
return ' '.join(str(int(num) * multiplier) if num.isdigit() else
num for num in text)
def GetUserInput():
'''Get S & multiplier. Test multiplier.isdigit(). Call
MultiplyText(text, multiplier)'''
text = raw_input('Enter some text: ')
while True:
multiplier = raw_input('Enter a multiplier: ')
try:
multiplier = int(multiplier)
break
except ValueError:
continue
return MultiplyText(text.split(), multiplier)
if "__name__" == '__main__':
GetUserInput()
What I did in IDLE:
>>>
>>> GetUserInput()
Enter some text: 4 times
Enter a multiplier: 2
'8 times'
>>>

If you change '__main__' to the name of the file, without the extension,
it will match __name__.
Alternatively, you can have an else after your `__name__ == '__main__'`
$ cat t1.py
if __name__ == '__main__':
print 'Executed from __main__'
if __name__ == 't1':
print 'Executed by import from t2'
$ cat t2.py
import t1
$ python t1.py
Executed from __main__
$ python t2.py
Executed by import from t2
$ cat t3.py
if __name__ == '__main__':
print 'Executed from __main__'
else:
print 'Executed by import'
$ cat t4.py
import t3
$ python t3.py
Executed from __main__
$ python t4.py
Executed by import
