Negative Indexing Use negative indexes to start the slice from the end of the string:

Dec 2, 2024 · Negative Indexing: Starts from -1 for the last element and goes up to -n for the first element. Strings in Python are also sequences so we can use negative indexing to access characters from the end of the string. Let's see some more examples of Negative Indexing.

Dec 31, 2024 · In this type of Indexing, we pass the Negative index (which we want to access) in square brackets. Here the index number starts from index number -1 (which denotes the last character of a string). Example 2 (Negative Indexing) : # declaring the string s = "Geeks for Geeks !"

Oct 25, 2019 · For negative indexing, the last character is at index -1, the next to the last at -2, etc. The best way to think about this is to get the last n characters of the string, you need to start at index -n .

Dec 2, 2024 · Slicing with Negative Numbers in Python. In Python, we can perform slicing on iterable objects in two ways first is using list slicing and the second is using slice() function. Python also allows programmers to slice the iterable objects using negative indexing. Let's first see the syntax of both methods. Using Slicing ( :) Using slice ...

Using a negative number as an index in python returns the nth element from the right-hand side of the list (as opposed to the usual left-hand side). so if you have a list as so: the print statement will print "e".

Jun 9, 2024 · You can use negative indexing to check if a string is a palindrome (a string that reads the same forward and backward). def is_palindrome ( s ): return s == s [:: - 1 ] print ( is_palindrome ( " radar " )) # Output: True print ( is_palindrome ( " python " )) # Output: False

Jun 9, 2023 · You can use negative indexing in Python with any sequence type, such as lists, strings, tuples, or ranges. You can also use negative indexing with slicing, which is a way of getting a...

Learn about negative indexing in Python and how it allows you to access elements from the end of a list or string. Explore the concept of negative indexing in Python and its applications in programming.

Mar 24, 2025 · Negative indexing allows developers to access elements in a sequence (such as lists, strings, and tuples) from the end of the sequence rather than from the beginning. This seemingly small feature can significantly enhance code readability and efficiency, especially when dealing with complex data manipulations.
