String Built-in Functions

                 Python includes the following built-in functions to manipulate strings:
                   len(): The len() function calculates and returns the length of a string supplied as an argument.
                   Syntax of using len() function is:

                   len(string_name)
                   lower(): The lower() function converts all uppercase letters to lowercase. Syntax of using lower()
                   function is:

                   string_name.lower()
                   upper(): The upper() function converts all lowercase letters to uppercase. Syntax of using upper()
                   function is:

                   string_name.upper()
                   capitalize(): The capitalize() function returns a string with the first character in capital. Syntax of
                   using capitalize() function is:

                   string_name.capitalize()

                  Program 10: To use various string built-in functions.


                     Program10.py

                  File  Edit  Format   Run   Options   Window     Help

                  str = 'Hello'
                  print(len(str))
                  print('Hello'.lower())
                  print('hello'.upper())
                  print('hello'.capitalize())




                 You will get the following output:

                     Output

                  5
                  hello
