From geeksforgeeks:
"PEP 498 introduced a new string formatting mechanism known as Literal
String Interpolation or more commonly as F-strings (because of the leading f
character preceding the string literal). The idea behind f-strings is to
make string interpolation simpler"
Example
name = 'Michael'
print(f"My name is {name}")
my_var = "world"
print(f"hello {my_var}")
# hello world
