❓ FAQ
QWhat argument does translate() require?
AA character-mapping translation table, usually generated by str.maketrans(). For example tbl = str.maketrans('aeiou', '12345'), then s.translate(tbl).
QCan it delete characters?
AYes. The third argument of maketrans specifies characters to delete: str.maketrans('', '', 'aeiou') combined with translate() can remove all vowels.
QWhat is the difference from replace()?
Atranslate() replaces or deletes characters one at a time via a character table, handling multiple character groups in one pass without overlapping matches; replace() replaces substrings. For mass single-character substitution, translate() is faster.
