String formatting methods

the following methods are applied to string objects

• .capitalize() - capitalizes the first character of a string
• .lower() - all characters of a string are made lowercase
• .upper() - all characters of a string are made uppercase
• .swapcase() - all characters of a string are made to switch case upper becomes lower and vice versa
• .title() - each 'word' separated by a space is capitalized

Formatting string input()

When storing input, sometimes a specific format is needed and formatting is applied to the input() function

Note: this technique overwrites the original user input in the variable with the formatted value
