Installation and Upgrade

  • Before You start, its highly recommended to update pip and setup tools:

python -m pip --upgrade pip
python -m pip --upgrade setuptools
  • to install the latest release from PyPi via pip (recommended):

python -m pip install --upgrade lib_list
  • to install the latest version from github via pip:

python -m pip install --upgrade git+
  • include it into Your requirements.txt:

# Insert following line in Your requirements.txt:
# for the latest Release on pypi:

# for the latest development version :
lib_list @ git+

# to install and upgrade all modules mentioned in requirements.txt:
python -m pip install --upgrade -r /<path>/requirements.txt
  • to install the latest development version from source code:

# cd ~
$ git clone
$ cd lib_list
python install
  • via makefile: makefiles are a very convenient way to install. Here we can do much more, like installing virtual environments, clean caches and so on.

# from Your shell's homedirectory:
$ git clone
$ cd lib_list

# to run the tests:
$ make test

# to install the package
$ make install

# to clean the package
$ make clean

# uninstall the package
