172 – Title case

Use the string method title to change a string’s casing to title case:

print("star wars: the empire strikes back".title())
# Star Wars: The Empire Strikes Back

Title case will modify the case of each word so that its first letter is uppercase and all other letters are lowercase. For some reason, I always think that title will only make sure the first letter of each word is uppercase, but it will actively lowercase letters that are not at the start of a word:

print("CrAzY CAsInG".title())
# Crazy Casing

A “word” is a sequence of alphabetical characters, so you can have numbers of punctuation between the letters that title will still uppercase those as separate words:

print("1word2words3words".title())
# 1Word2Words3Words
