how to capitalize a letter in a string in python code example

# Python string capitalization
string = "this isn't a #Standard Sntence."
string.capitalize() # "This isn't a #standard sentence."
string.upper() # "THIS ISN'T A #STANDARD SENTENCE."
string.lower() # "this isn't a #standard sentence."
string.title() # "This Isn'T A #Standard Sentence."

from string import capwords
string = capwords(string) # capitalize characters after each separator.
# see the doc: string.capwords(s, sep=None), separator defaults to space

# or implement it directly:
