Writing requirements.txt

We covered how having a requirements.txt file can help your package be more portable by allowing your users to easily recreate its intended environment. In this exercise, you will be writing the contents of a requirements file to a python variable.

Note, in practice, the code you write in this exercise would be written to its own txt file instead of a variable in your python session.
