AttributeError: 'function' object has no attribute 'my_args'

How can I get access to my_args list data type in __main__?

test1.py开发者_JAVA百科

#!/usr/bin/env python

def main():
    print 'main function'
    one()

def one():
    print 'one function'
    my_args = ["QA-65"]

def two():
    print 'two function'

if __name__ == "__main__":
    main()
    getattr(my_args, pop)

You can if you return them from one():

#!/usr/bin/env python

def main():
    print 'main function'
    args = one() # returns my_args, which i'm assigning to args
    print 'i got args from one():', args
    print args.pop()

def one():
    print 'one function'
    my_args = ["QA-65"]
    return my_args

def two():
    print 'two function'

if __name__ == "__main__":
    main()
    #getattr(my_args, pop)
    # ^^^ Moved this up to main() ^^^

Outputs:

main function
one function
i got args from one(): ['QA-65']
QA-65

You can do this using global.

#!/usr/bin/env python

def main():
    print 'main function'
    one()

def one():
    print 'one function'
    global my_args
    my_args = ["QA-65"]

def two():
    print 'two function'

if __name__ == "__main__":
    main()
    print my_args.pop()

Demo.

Just because you can doesn't mean you should!
