Installing Python dependencies from behind a corporate proxy

django_proxy.py

Hi,

So recently I had a need to install Django on my corporate machine. 
Since I was connected to the Internet from behind a proxy, I encountered connection errors. 
I will state what I did to get this to work.

#Problem:
Unable to install Python dependencies from behind a proxy

#Assumptions
1. You have got the proxy connection details
2. Your username may contain the @ symbol.
  - In the password, replace the '@' with '%40'

##Solution
#Install Django (Example 1)
pip --proxy http://username:password@ipaddress:port install --trusted-host pypi.org --trusted-host pypi.python.org --trusted-host files.pythonhosted.org django

#Upgrade PIP (Example 2)
pip --proxy http://username:password@ipaddress:portinstall --trusted-host pypi.org --trusted-host pypi.python.org --trusted-host files.pythonhosted.org --upgrade pip

Note:
1. Where the password contains the '@' symbol replace it with '%40'
2. Where there is a timeout, you may use the option '--default-timeout=100'
