How To Format String In Python

In this tutorial, we’ll learn how to easily format string in Python. We’ll going through multiple methods and examples to understand how to practically format string in Python.

Introduction: Format String In Python

It specifies adding new data dynamically in a string with proper formats. Let’s discuss about the multiple methods which can be used to format string in Python.

3 Ways To Format String In Python

Let’s discuss about 3 different ways for string formatting in Python programming language. These are listed below:

• % Operator
• Python String format() Method
• f-String

Method 1: % Operator

This symbol % is also known as ‘string formatting operator’. Its an old method to format a Python string. See below example:

print('This is %s Programming' %'Python')

Output

This is Python Programming

We’ve specified a string ‘Python’ and have used it inside the main string using %s.

• %s is for strings
• %d is for integers
• %f is for floating point values
• %b is for binary format

We can also inject multiple values. See below examples:

print('This is %s Programming %s' %('Python','Language'))
print('This is %s Programming %d' %('Python',3))
print('This is %s %d %s' %('Python',3,'Programming'))
print('This is Python Programming %d' %3)
print('This is %s Programming %f' %('Python',3.0))
name='Python'
print('This is %s %d' %(name,3))

Output

This is Python Programming Language 
This is Python Programming 3 
This is Python 3 Programming 
This is Python Programming 3 
This is Python Programming 3.000000 
This is Python 3

Method 2: Python String format Method

This method can be used to inject data specified in it into main string using placeholders. These placeholders are specified using curly braces {}. See below examples: Continue reading…
