Negative Indexation

In the preceding chapter, it appeared that we were counting letters to determine the index corresponding to each letter. If we intend to access the final symbol, manual counting may seem cumbersome.

Python, however, is considerate and anticipates our needs. Consequently, it introduced negative indexing. To obtain the last character of a word, it is advisable to utilize the syntax word[-1].

Note

The negative indexation starts from -1, then -2, etc. word[-0] is the same as word[0] for Python.

A small piece of advice: We can mentally divide a string into two parts and use positive indexation for the left-hand part and negative indexation for the right-hand part, but it's always up to us.😏
