python pip install calling module by name in terminal

I've noticed that for some packages, for example, ipython and termdown, after I've successfully installed them with pip install, they can be immediately invoked from the terminal. e.g:



$ termdown 100


I understand that the primary file within these packages are operated by the #! shebang line and hence callable, however, where in the python directory are the hook that allowed them to become callable stored? e.g. a /bin folder where everything can be invoked from the terminal? Or is there some other mechanism like PATH in play? Thanks!

          Generally when a Python package is installed via pip, setuptools, etc. two mechanisms can be invoked within the packages setup.py file to produce a CLI executable command:



          The scripts keyword argument and the console_scripts entry point.



          Usually a symlink is created within /usr/local/bin that points back to the installed package.
