How Can I Split a String in Python Using a Specific Delimiter?

Splitting Strings by Delimiters in Python

When working with strings in Python, it often becomes necessary to split them into smaller segments based on specific delimiters. One such scenario is splitting a string every time a particular delimiter appears, dividing the string into a list of substrings.

Problem:

Given the input string "MATCHES__STRING," we aim to split it wherever the "__" delimiter occurs. The desired output would be a list of two strings: ['MATCHES', 'STRING'].

Solution:

Python offers an elegant way to split strings using the str.split method. This method takes a single string as input and splits it into a list of substrings based on the specified delimiter.

To split on a specific delimiter, simply pass it as an argument to the str.split method:

input_string = "MATCHES__STRING"
delimiter = "__"
split_result = input_string.split(delimiter)

This code snippet will assign the split result to the split_result variable, which will contain the desired list of substrings:

['MATCHES', 'STRING']

By leveraging the str.split method, we can conveniently split strings on any character or string delimiter, making it an essential tool for a variety of string manipulation tasks in Python.
