String Formatting Operator: in Python

One of Python’s coolest features is the string format operator %. This operator is unique to strings and makes up for the pack of having functions from C’s printf() family.

Example:

#!/usr/bin/python

Print “My name is %s and weight is %d kg!” % (‘zara’, 21)

This produce following result:

My name is Zara and Weight is 21 kg!

Here is the list of complete set of symbols which can be used along with %:
