To remove a character from a string in Python, use replace() with an empty string: text.replace(“-“, “”) removes every hyphen. To remove several different characters at once, use text.translate(str.maketrans(“”, “”, “-()”)) or re.sub(r”[-()]”, “”, text). Strings are immutable, so each method returns a new string that you must assign. This guide covers removing a character … Read more >>
