Passing Tuples to startswith

Sep 13, 2023

Here's another thing that linting taught me recently: Python's str.startswith() method, and str.endswith() as well, takes a tuple as the first parameter! This makes checking for multiple options really simple:

# Verbose way of writing it
if (mystring.startswith('c.') or mystring.startswith('m.') or mystring.startswith('s.')):

# Easier way
if (mystring.startswith(('c.', 'm.', 's.'))):

I didn't realize the language allowed this!
