Jan 24, 2025 · Learn how to perform case-insensitive string comparisons in Python using methods like lower(), upper(), casefold(), and regular expressions. Includes practical examples!

Sep 15, 2008 · What is the easiest way to compare strings in Python, ignoring case? Of course one can do (str1.lower() <= str2.lower()), etc., but this created two additional temporary strings (with the obvious alloc/g-c overheads).
