string interpolation in Python

Python 3.6 added new string interpolation method called literal string interpolation and introduced a new literal prefix f.
This new way of formatting strings is powerful and easy to use. It provides access to embedded Python expressions inside string constants.
String interpolation is a process substituting values of variables into placeholders in a string.

Example:

stock_price = 1100
print(f"Today's price for stock is: {stock_price}")

Output:

Today's price for stock is: 1100
