Crafting a docstring

You've decided to write the world's greatest open-source natural language processing Python package. It will revolutionize working with free-form text, the way numpy did for arrays, pandas did for tabular data, and scikit-learn did for machine learning.

The first function you write is count_letter(). It takes a string and a single letter and returns the number of times the letter appears in the string. You want the users of your open-source package to be able to understand how this function works easily, so you will need to give it a docstring. Build up a Google Style docstring for this function by following these steps.
