Many developers are not necessarily aware that the startswith and endswith methods of str objects can accept a tuple of strings to match. This means that there is a lot of code that uses boolean expressions such as x.startswith('foo') or x.startswith('bar') instead of the simpler expression x.startswith(('foo', 'bar')).

This codemod simplifies the boolean expressions where possible which leads to cleaner and more concise code.

The changes from this codemod look like this:

 x = 'foo'
- if x.startswith("foo") or x.startswith("bar"):
+ if x.startswith(("foo", "bar")):
 ...
