Abort execution of a module in Python

There is no good way to stop execution of a module. You can raise an exception, but then your importing module will need to deal with it. Perhaps just refactor like this:

print(' module1')some_condition = Trueif not some_condition:  print(' module2')

Update: Even better would be to change your module to only define functions and classes, and then have the caller invoke one of those to perform the work they need done.

If you really want to do all this work during import (remember, I think it would be better not to), then you could change your module to be like this:

def _my_whole_freaking_module():    print(' module1')    some_condition = True    if some_condition:        return    print(' module2')_my_whole_freaking_module()

My main.py looks like this,

print 'main 1'try:    import my_moduleexcept ImportError:    passprint 'main 2'

and my_module.py looks like this,

print 'module 1'if True:    raise ImportErrorelse:    passprint 'module 2'

output is,

main 1module 1main 2

You can wrap the module code inside function, like this:

def main():  print(' module1')  some_condition=True  if some_condition:    return  print(' module2')main()
