[Example code]-I am trying to upload a youtube video using the Youtube API with python

As already mentioned in one of my comments above, I suspect that you’re running your program on a computer that has at least two Python installations — each set up with own (separate) Google API Client Library for Python packages –, and that your program is actually running an old version of the client library.

I suggest to verify the version of the client library at run-time. Do that by inserting the following piece of code right at the beginning of main function:

print('google-api-python-client version:',       get_googleapiclient_version())

where the function get_googleapiclient_version is:

def get_googleapiclient_version():    try:        import googleapiclient        return googleapiclient.__version__    except AttributeError:        import pkg_resources        return pkg_resources.get_distribution(              "google-api-python-client").version

The version numbers shown should be newer than 1.6.7 from Apr 27, 2018.

The best would always be to make sure you’re running the latest version. (At the time of this writing that is 1.10.0 from Jul 15th.)

A caveat of function get_googleapiclient_version above: using pkg_resources is not one hundred percent a reliable method for obtaining a package’s version. In any case, the following piece of code prints the path of googleapiclient:

print('google-api-python-client path:',       googleapiclient.__path__)

This may help troubleshoot the real origin of the client library your program is actually running.
