3An f-string stands for 'function-string' it's just used to work with 
4strings more appropiately, they do the exact same job as concantenating
5strings but are more efficient and readable.

8# Concantenating strings:

10Age = "25"

14# Using f strings:
15
16Age = 25
17
18print(f"I am {Age} years old.")
19
20# ^ notice the letter 'f' at the begining of the string.
21# That defines the string as being an f-string.

24# .format()
