Why not pip freeze?

• pip freeze only saves the packages that are installed with pip install in your environment.
• pip freeze saves all packages in the environment including those that you don’t use in your current project (if you don’t have virtualenv).
• and sometimes you just need to create requirements.txt for a new project without installing modules.
