New submission from Joe Borg:
See example:
>>> import argparse
>>> a = argparse.ArgumentParser()
>>> b = a.parse_args([])
>>> if b != None:
... print "hey"
File "<stdin>", line 2
print "hey"
^
SyntaxError: invalid syntax
>>>
>>> if b != None:
... print("hey")
...
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
