The Split Function In Python

Python is the best and easy language to start with and is famous worldwide for its application and easy implementation. Python is a high-level, general-purpose, portable language that is easy to use. The language is similar to the formal language and makes it easy to learn. The python programming applications vary from field to field. Application of Python is in web application development, Artificial Intelligence, Machine Learning, cutting-edge technology, digital image processing, new software development, etc. As of 2022, the latest version is python3. It is one of the best beginner programming languages. let us know about that the The Split Function In Python.

Python Functions

Functions are used most commonly for easy programming. Python has many built-in functions that make programming easy. Python functions are easy to write. Function names follow the same rules as that variable naming rules. So, a function is a block of related statements. It is to perform logical, computational, and different tasks. 

Coding is hard when the same step has to repeat. Functions make the job easy. Function calls help to reuse the code that reusability is possible with functions. It helps the program to be short, easy to understand, can be edited easily, non-repetitive, more organized and makes the code readable. There are mainly two types of functions. They are

  1. Built-in functions 

Functions that are already available for a programming language are known as built-in functions.

  1. User-defined function

Functions that are defined by the user according to the need are known as user-defined functions.

Split function in Python


Strings are a collection of characters. That is, strings are like arrays of bytes in other programming languages. Python does not have character types like integer, character, etc. It is automatically detected. A string of length “one” is said to have a single character.

Split() function

The split() function is for string manipulation. It is to break a string into several small strings known as substrings. The split () function returns a string as a list. The split() function separates the given string according to the separator (Separators are special characters like “,”, “:”, “@”, etc..) that are already defined.

Why is it relevant to use the Split() Function in Python?

  • If a string has to be split into several substrings, the split() function is used.
  • The split () function can be used and still works if the separator is not specified.

Syntax of split() function

The syntax or the structure of split() is given as, 

split(separator, max) 

Here, the separator is the delimiter, based on the given string that is separated and Max is the number of times a given string is divided. Max is -1 as default. 

Working of the Split() function has the following steps

Using the split() function, string manipulation is done. All the programs that deal with strings need a split() function. The working of the split() function is as follows: 

  • The split () function starts working by scanning a given string and the scanning is done based on the separator. The separator passes the parameter to the split() function.
  • The white spaces pass as a separator other than the special characters.
  • The programmer can give the number of times a string has to divide using the split() function.
  • The whole string is scanned and divided based on the delimiter if the number is not specified by the user.
  • When the function is called, it returns the substring. The elements of the list are returned as a result of a function call.

What are the different ways to use the split function?

The uses of a ‘split’ function are

  • delimiter space
  • delimiter comma
  • delimiter hash
  • delimiter tab
  • delimiter new line character
  • the initial appearance of a character
  • file into a list
  • multiple delimiters
  • one of the substrings from the given string as the delimiter.
  • the max split parameter
  • Splitting a string into a list and a character array

Here are some example of split function in Python

Consider the given python code and the corresponding output

x = ‘red,green,blue’


 >>>[‘red’, ‘green’, ‘blue’]

>>> a,b,c = x.split(“,”)

>>> a


>>> b 


>>> c


Here, in this code, the split() function divides the originally given string. The string includes three colors, red, green, and blue, and it stores each variable in a separate string(a, b, and c). When the variable is given, the output is provided as the corresponding color.


Python is a simple, powerful, general-purpose, object-oriented, interpreted scripting language. Guido Van Rossum founded Python. Python split() function is to separate a string into several substrings. It returns a list of all the words in the given string. The programmer can give the number of times to split the string. Split() functions help to reduce the complexity of the program by splitting a complex string into several substrings. 

Frequently Asked Questions
  1. What is Python?

Python is a programming language. It is one of the popular languages used worldwide with a wide variety of applications in the IT industry.

  1. Are concatenation and split functions different in python?

The split function is to split or divide a sentence or string or a list. But, concatenation is merging the whole substrings into one, that is to form a large string from several small strings. The split() function is just the opposite of concatenation. 

  1. What are the arguments of a function?

Arguments of a function are the values that pass inside the parentheses of a function. A function includes any number of arguments that are separated by a comma.

  1. What are the advantages of split functions?

Split() functions have the advantage of making the coding easy when splitting a long string into several substrings.
