String Formatting Mini-Language The String Formatting Language in Python is a powerful way to tailor the display of strings and other data structures. This string formatting mini language works for f-strings and .format().

Take a look at some of these examples!

>>> my_num = 2134234523
>>> print(f"{my_num:,}")

>>> my_smaller_num = -30.0532234
>>> print(f"{my_smaller_num:=09.2f}")

>>> my_str = "Center me!"
>>> print(f"{my_str:-^20}")
-----Center me!-----

>>> repr_str = "Spam \t Ham"
>>> print(f"{repr_str!r}")
'Spam \t Ham'
