Update all pip packages!

update-pip-advanced.py

#!/usr/bin/env python

import os 
import pip

dists = []
for dist in pip.get_installed_distributions():
    dists.append(dist.project_name)

for dist_name in sorted(dists, key=lambda s: s.lower()):
    cmd = "sudo pip install {0} -U".format(dist_name)
    print '#', cmd
    #os.system(cmd)

import pip
from subprocess import call
 
for dist in pip.get_installed_distributions():
    call("pip install --upgrade " + dist.project_name, shell=True)

Very nice script. I added some small changes:

#!/usr/bin/env python

import os 
import pip

dists = []
for dist in pip.get_installed_distributions():
    dists.append(dist.project_name)

for dist_name in sorted(dists, key=lambda s: s.lower()):
    cmd = "sudo pip install {0} -U".format(dist_name)
    print '#', cmd
    #os.system(cmd)

Packages are sorted in ascending order by name in an ignore-case way. I use it to update packages globally, that's why the "sudo". If you execute it, it will simply print the commands (dry run). If they are OK, uncomment the last line.
