2. Get Substring of a String using Slicing Slicing is a built-in Python feature that allows you to extract a substring from a string by specifying its start and end indices. The resultingstringwill include all the characters from the start index up to, but not including, the end index. ...
To get a substring of a string in Python, you can use the string[start:end] notation. This will return a new string that is a copy of the original string, starting from the character at the start index and going up to, but not including, the character at the end index. For example...
Substring in Python language is a sequence of characters with one more string. It is also termed as ‘Slicing of String’. Python’s array functionality known as ‘slicing’ can be applied to our strings. Slicing is a broad spectrum of functionality that can be used in any array-type objec...
