# Use Python without activating or fixing the prefixes. Most Python
# libraries will work fine, but things that require prefix cleanups
# will fail.
./my_env/bin/python

# Activate the environment. This adds `my_env/bin` to your path
source my_env/bin/activate

# Run Python from in the environment
(my_env) $ python

# Note that this command can also be run without activating the environment
# as long as some version of Python is already installed on the machine.
