Python provides us with three methods to facilitate case conversion of strings.
- title()
- lower()
- upper()
python title() method
The title() method is used to capitalize the first letter of each word in a string and convert all other letters to lowercase. If there are no characters to be converted, the string is returned unchanged.
python lower() method
The lower() method is used to convert all uppercase characters in a string to lowercase. If there are no characters to be converted, the string is returned unchanged.
python upper() method
The upper() method is used to convert all lowercase characters in a string to uppercase. If there are no characters to be converted, the string is returned unchanged.
Note that all three methods are limited to returning the new converted string and do not change the original string.
