Python utils I like to have.
As submodule
git submodule add https://github.com/lakazatong/python_utils
As source
git clone https://github.com/lakazatong/python_utils
git submodule update --remote --merge
path=python_utils && git submodule deinit -f path && rm -rf .git/modules/path && git rm -f path
Taken from here.
