What Is String In Python?

Strings in Python are an array of characters that are written in single, double, or triple quotes. This is the same as the meaning of the string in many other programming languages. Read on to find out what string means in Python. 

What Is A String?

A string is a set of Unicode characters which are grouped together and bring more uniform encoding. Strings are created by placing characters inside quotation marks.

How to Declare String In Python?

Below is the sample code on how to declare a string in python.

Sample code:

var1 = 'Single Quotes'

var2 = "Double Quotes"

var3 = '''Triple Quotes'''


Single Quotes 
Double Quotes
Triple Quotes

Python String 

The string in Python is a data type, but it is not a character data type. It is an array of characters that are in Unicode representation. You can also apply all of the list functions to a string in Python.

You can easily add a python string to Python by adding the word that you want to declare a Python string between quotation marks. This is how you define a Python string. A list in the memory will be made.

You can define a string in Python using either single or double quotation marks. There are a few ways the Python string will use the string.

Sample Code

str1 = 'Using single quotation'

str2 = ''Using double quotation''

For instance, if you want to validate that the email string is lowercase, you will need to use the built-in function Python provides, which converts that string to lowercase.

Sample Code

var1 = "[email protected]"


[email protected]

This is used if users are registered to the application using their email address, and you want to ensure that there are no duplications where there have been differences in upper and lower case letters.

In this case, all of the letters in the string will be converted to lowercase.

Strings Are Arrays Of Bytes

Strings that are used in Python refer to arrays of bytes that are used to represent unicode characters.

Python strings are nice and simple as they do not have a character data type, a single character is referred to as a string with a small length.

If you are hoping to view or gain access to certain parts of the string then you will be able to use square brackets in order to do so.

Understanding String Length

If you are looking for information on the length of a string, then you will need to use the len() function. This will tell you the length of the string.

Sample Code

string = "pythonforfree"



Keywords In Strings In Python

Keywords are great for finding the information you need within a string. For instance, you can use the keyword ‘in’ to find out if there is a certain word or phrase in the string.

You can also use the word ‘if’ to display the string if a certain word is present. You can also use ‘not in’ to find out if certain words are not in the string. 

How To Reverse A String 

In order to reverse a string in Python, you need to understand how to read the string in Python. In Python, a string is seen as a list of characters and so to reverse this string is quite simple.

Using a code, you can create the string and then reverse it. There are a couple of different ways that you can reverse a string.

How To Format String In Python

There are many different ways to format strings in Python. These include: 

  • Formatting with the % operator
  • Formatting with f-strings
  • Formatting with string template class
  • Formatting with the format() method

Frequently Asked Questions

What Is Python?

Python is a programming language that is very popular. It is used by YouTube, Google, and many other people. It is simple and easy to use, and very cost-effective.

The coding is very readable when compared to other programming languages, and it is therefore accessible to lots of different types of people. It is innovative and forward-thinking. 

What Is The History Of Python?

Python was developed in the 1980’s and first was released to the public in 1991. It was developed by Guido Rossum who created Python under the Python Software Foundation.

The company focussed completely on the readability of codes and the ease of the syntax that is used by the company.

The code that is used means that it is easy to express whatever you’re hoping to express on just a few lines without having to continue for ages. 

The company was introduced because Guido Van Rossum was completing it as a hobby during his Christmas holidays and it grew into something much bigger than anyone expected. 

Why Python?

Python is extremely popular because it is very easy to use, and it produces high productivity in programming. It is also affordable and very economical.

When you are using Python, due to the simple language, it is very easy to troubleshoot any problems that you might encounter, and these problems are always easy to fix.

There is even a troubleshooting service built into Python.
