Negative indexing means to accessing elements in reversing order(end of the sequence) lik string or list

Negative indexing in Python is a way to count elements from the end of a list, string, or other sequence.

  • The last element is at index -1.
  • The second-to-last element is at index -2.
  • And so on...

For example, if you have a list my_list = [10, 20, 30, 40, 50]:

  • my_list[-1] gives you the last element, which is 50.
  • my_list[-2] gives you the second-to-last element, which is 40.

Yes, absolutely. Negative indexing in Python is often used in combination with slicing to extract sub-sequences from a larger sequence.

You are correct, negative indexing in Python is primarily used for slicing operations to access substrings or sublists from a sequence starting from the end.

In Python, slicing allows you to extract a portion of a string, list, or tuple by specifying the start and end indices. Negative indexing can be combined with slicing to begin the slice from the end of the sequence.
