Dropbox function not importing or working from other local file

Question

I have two python files, one where I have written and store functions and another where they are used.

The ‘HW’ function imports and runs, however the dbxupld does not. Can anyone suggest how I could get this to work. Many thanks.

Python_script1.py

def HW():
    print('Hello, World!')


def dbxupld(FileFROM,FileTO):
    import dropbox

    class TransferData:
        def __init__(self, access_token):
            self.access_token = access_token
        def upload_file(self, file_from, file_to):
            dbx = dropbox.Dropbox(self.access_token)
            with open(file_from, 'rb') as f:
                dbx.files_upload(f.read(), file_to)

    def main():
        access_token = "[access code hidden]"
        transferData = TransferData(access_token)
        file_from = FileFROM
        file_to = FileTO
        transferData.upload_file(file_from, file_to)

    if __name__ == '__main__':
        main()

Python_script2.py

from Python_script1 import HW
from Python_script1 import dbxupld

HW()

FileFROM = '/home/Setup stuff.pdf'
FileTO = '/upload_testing/Setup Stuff.pdf'
dbxupld(FileFROM,FileTO)

Out:

Hello, World!

But no dropbox upload

The function is being imported correctly. The problem lies in this part:

if __name__ == '__main__':
    main()

Since you're importing Python_script1 inside Python_script2, the value of __name__ inside Python_script1 is Python_script1 and not __main__. The condition is not met and main never gets called. To make this work, remove the condition if __name__ == 'main'.

For more information about __main__ and __name__, refer https://docs.python.org/3/library/main.html
