How to find the most common element in a list in Python?
Example: With so many solutions proposed, I’m amazed nobody’s proposed what I’d consider an obvious one (for non-hashable but comparable elements) — [ itertools.groupby ] [1]. itertools offers fast, reusable functionality, and lets you delegate some tricky logic to well-tested standard library components. Consider for example:
