update all your python packages via pip

gistfile1.txt

# pip doesn't have a command to update all python packages yet, so you can use the code below for now
# big command right? make an alias. Oh, you maybe need to put "sudo" before "pip install"

$ (echo pip; pip freeze | awk 'BEGIN{FS="=="}{print $1}') | xargs pip install -U

I think you could change first part to

echo pip; pip freeze | cut -d= -f 1

getting:

$ (echo pip; pip freeze | cut -d= -f 1) | xargs pip install -U
