Strings Formatting in Python

Rahul Gupta — Tue, 03 Jan 2023 11:54:49 +0000

String formatting is the process of infusing things in the string dynamically and presenting the string.

There are 3 different methods to format a string in string

Old style formatting
String Format method
F-string / String interpolation

Old style formatting technique

In this technique we need percent symbol % followed by some characters inside the string as placeholder for the values that will be embedded in string.
There are four placeholder or special symbols:
%s → string
%d → integer
%f → float
%.(n)f → for floating value with n digit precision (n is a positive integer)
These symbols are similar that use in c programming language.

Example 1:

a=5
b=3
print(‘%d + %d = %d’%(a,b,a+b))
# 5+ 3 = 8

Example 2:

name= ‘Anuj’
like=’Bikes’
print(‘My name is %s. I like %s’%(name,like))
# My name is Anuj. I like Bikes.

String format Method

In this technique we use string format method. To use format method we need to use pair of empty curly bracket {} for each variable we need to embed in the string at place of brackets

Example 1:

a=5
b=3
print(‘{} + {} = {}’.format(a,b,a+b))
# 5+ 3 = 8

Example 2:

name= ‘Anuj’
like=’Bikes’
print(‘My name is {}. I like {}.’.format(name,like))
# My name is Anuj. I like Bikes.

F-string / Literal string interpolation

To create an f-string, prefix the string with the letter “ f ”. The string itself can be formatted in much the same way that you would with str.format().

Example 1:

a=5
b=3
print(f.‘{a} + {b} = {a+b}’)
# 5+ 3 = 8

Example 2:

name= ‘Anuj’
like=’Bikes’
print(f.‘My name is {name}. I like {like}’)
# My name is Anuj. I like Bikes.

A programming language is required if you wish to work in the computer industry. If you are unsure about which programming language to use, I have included some beginner-friendly programming languages below.

Note: Learning and mastering one language is the ideal option for beginners.

C++

C++ is a cross-platform language that can create high-performance applications. C++ was developed by Bjarne Stroustrup, as an extension to the C language.

Advantages-

It gives programmers a high level of control over system resources and memory.
It can be found in today's operating systems, Graphical User Interfaces, and embedded systems.
It is an object-oriented programming language that gives a clear structure to programs and allows code to be reused, lowering development costs.
It is portable and can be used to develop applications that can be adapted to multiple platforms.

Python

Python is a popular programming language. It was created by Guido van Rossum, and released in 1991.

Advantages-

It has a simple syntax similar to the English language.
Its syntax allows developers to write programs with fewer lines than some other programming languages.
It can be used on a server to create web applications.
It can be used alongside software to create workflows.

Java

Java is a popular programming language, created in 1995. It is owned by Oracle, and more than 3 billion devices run Java.

Advantages-

It has a large demand in the current job market
It is easy to learn and simple to use
It has huge community support (tens of millions of developers)
It's used for various purposes like mobile applications development, desktop application development, and many others.

JavaScript

JavaScript is the world's most popular programming language. JavaScript is the programming language of the Web.

Advantages-

It is a simple and easy-to-use programming language.
It is one of the world's most popular programming languages.
It is used by many famous companies.
It is a versatile language that can be used for front-end as well as back-end development.
