10 – Remove punctuation from a string#

Don’t use the method replace to remove punctuation from a string. Instead, use the method translate.

The method translate is an efficient and general-purpose method for replacing (or removing) multiple characters in a string simultaneously.

The method translate expects a “translation table” argument in a very specific format, but the string class method maketrans can build that for us:

import string

# print(string.punctuation)  # !"#$%&'()*+,-./:;<=>?@[\]^_`{|}~
punctuation_removal = str.maketrans("", "", string.punctuation)

s = "Hello, world!"
print(s.translate(punctuation_removal))
# Hello world
