Capitalize string
Python, String · Nov 2, 2020
Capitalizes the first letter of a string.
- Use list slicing and
str.upper()to capitalize the first letter of the string. - Use
str.join()to combine the capitalized first letter with the rest of the characters. - Omit the
lower_restparameter to keep the rest of the string intact, or set it toTrueto convert to lowercase.
def capitalize(s, lower_rest = False):
return ''.join([s[:1].upper(), (s[1:].lower() if lower_rest else s[1:])])capitalize('fooBar') # 'FooBar'
capitalize('fooBar', True) # 'Foobar'
