Variables and Strings

Variables are used to store values. A string is a series of characters, surrounded by single or double quotes.
Hello world print("Hello world!")
Hello world with a variable msg = "Hello world!" print(msg)
Concatenation (combining strings)
    first_name = 'albert'
    last_name = 'einstein'
    full_name = first_name + ' ' + last_name
    print(full_name)
