I recommend `assertStartsWith()` and `assertEndsWith()`, both for readability and for accessibility – screen readers will have a better chance with the extra capitals and it helps people with dyslexia and cognitive disabilities.

It doesn’t really matter that `str.startswith` is all lower case, because we’re creating a new method name.

All the other [methods](https://docs.python.org/3/library/unittest.html#assert-methods) follow the same capitalisation rule.

For example, the one that checks checks `isinstance` is `assertIsInstance` and not `assertIsinstance`.

Here’s similar accessibility advice about hashtags:
