Python String capitalize() Method
The str.capitalize() method capitalize (converts to titlecase) the first character of the string and keeps all the other characters in lowercase.
Note: From Python 3.8 onwards, the first character is converted into titlecase instead of uppercase. This means the digraphs will only have the first letter capitalized instead of the full character.
Example:
text ="python Is BEST"
captialized_text= text.capitalize()
print(captialized_text)Output
