String Format
As we learned in the Python Variables chapter, we cannot combine strings and numbers like this:
But we can combine strings and numbers by using f-strings or the format() method!
F-Strings
F-String was introduced in Python 3.6, and is now the preferred way of formatting strings.

A placeholder can include a modifier to format the value.
A modifier is included by adding a colon : followed by a legal formatting type, like .2f which means fixed point number with 2 decimals:
A placeholder can contain Python code, like math operations:
