full_name = first_name + ' ' + last_name
        

2. String Methods

Python provides various string methods for manipulation.

my_string = 'Hello, World!'
uppercase_string = my_string.upper()
        

Common string methods include:

string_length = len(my_string)
substring_index = my_string.find('World')
