How do I put a variable’s value inside a string (interpolate it into the string)?

In Python, you can use the format() method or f-strings (available in Python 3.6 and above) to interpolate a variable's value into a string.

Using the format() method:

Interpolate a variable's value into a string using the format() method

Using f-strings (Python 3.6 and above):

Interpolate a variable's value into a string using the f-strings

Both will output "My name is John".
