Splitting a String by a Delimiter in Python

Often, you'll encounter situations where strings need to be split into smaller segments based on a specific delimiter. This guide provides a concise solution to this common programming challenge.

Problem Statement

Given an input string, for instance:

'MATCHES__STRING'

Split the string wherever the delimiter "__" appears, resulting in a list of two substrings:

['MATCHES', 'STRING']

Solution

To achieve this, utilize Python's str.split method:

string.split(delimiter)

For the given example, the code would be:

"MATCHES__STRING".split("__")

This code will split the string at each occurrence of the "__" delimiter, yielding the desired output:

['MATCHES', 'STRING']
