+# F-string (String Format) allows you to format selected parts of a string. 
+# To specify a string as an f-string, simply put an f in front of the string. 
+# To format values in an f-string, add placeholders {}, a placeholder can contain variables, operations, functions, and modifiers to format the value.
+
+# A placeholder can also 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.
