Before Python 3.2, you could only create fractions from real numbers using the .from_float() and .from_decimal() class methods. While not deprecated, they’re redundant today because the Fraction constructor can take both data types directly as an argument:...

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 ...
