all Python 3Strings (str)function

str.rstrip

stripping

Return a copy with trailing characters removed (whitespace by default).

Syntax

s.rstrip([chars])

Same trap as lstrip, mirrored: the argument is a character set, so 'test.txt'.rstrip('.txt') returns 'tes'. Use str.removesuffix() (Python 3.9+) when you mean a suffix as a whole. Bare rstrip() is convenient for dropping the newline off a line read from a file, but it also eats meaningful trailing spaces if your data carries any.

Examples

print('hi  '.rstrip())     # → hi
print('hixx'.rstrip('x'))  # → hi
print('--a--'.rstrip('-'))  # → --a
