The % option multiplies a number by 100 and displays it in fixed-point format, followed by a percentage sign.The % option should always go at the end of your formatting specification, and you can’t mix it with the f option. For example, .1% displays a number as a percentage with ...
Except switches to 'E' if the number is large. % Percentage. Multiples by 100 and puts % at the end. Example 2: Simple number formatting # integer arguments print("The number is:{:d}".format(123)) # float arguments print("The float number is:{:f}".format(123.4567898)) # octal, ...
