Creating a Python requirements.txt File

This can be done quickly by typing:

$ pip freeze >requirements.txt

at the command line.

To install packages using a requirements file just use pip:

$ pip install -r requirements.txt

To check if the packages in your requirements.txt file are up-to-date use:

$ pip list --outdated

and to update those packages:

$ pip install -U <packagename>

This process has some drawbacks as packages are sometimes included that are no longer needed and should only be used initially and then maintained manually.
