The syntax of title() is:
str.title()
title() Parameters
title() method doesn't take any parameters.
Return Value from title()
title() method returns a title cased version of the string. Meaning, the first character of each word is capitalized (if the first character is a letter).
Example 1: How Python title() works?
text = 'My favorite number is 25.' print(text.title()) text = '234 k3l2 *43 fun' print(text.title()) Output
My Favorite Number Is 25. 234 K3L2 *43 Fun
Example 2: title() with apostrophes
text = "He's an engineer, isn't he?" print(text.title()) Output
He'S An Engineer, Isn'T He?
title() capitalizes the first letter after apostrophes as well.
To solve this issue, you can use regex as follows:
Example 3: Using Regex to Title Case String
import re def titlecase(s): return re.sub(r"[A-Za-z]+('[A-Za-z]+)?", lambda mo: mo.group(0)[0].upper() + mo.group(0)[1:].lower(), s) text = "He's an engineer, isn't he?" print(titlecase(text)) Output
He's An Engineer, Isn't He?
