Python and Proxies

PIP (primary package manager for python) will use the following locations on windows:

• User: C:\Users\<<username>>\pip\pip.ini
• User: C:\Users\<<username>>\AppData\Roaming\pip\pip.ini
• System: C:\ProgramData\pip\pip.ini

Create a pip.ini file in one of these locations, and then copy these contents into it:

    [global]
    trusted-host = pypi.python.org
                   pypi.org
                   files.pythonhosted.org
    proxy = http://internet.proxy.fedex.com:3128
