Suppose you want to extract or slice the string part‘I live’. First, you need to count the number of characters, including space (consider space a character), in the part you want to extract; it contains 6 characters. One thing to remember is that slicing starts from index 0, which ...
You can also use negative index numbers to slice a string. As we went through before, negative index numbers of a string start at -1, and count down from there until we reach the beginning of the string. When using negative index numbers, we’ll start with the lower number first as it...
TypeError: unhashable type: 'slice' in Python Fix TypeError: unhashable type: 'slice' in Python Conclusion Slicing is a very common technique in Python. It allows us to extract data from a given sequence like a string, list, tuple and more, using the indexes of the elements. ...
Python is the world’s leading programming language for data analysis for a reason: it’s versatile, powerful, intuitive, and relatively easy — and the open source language has libraries and add-ons that are kept up-to-date by programmers and analysts all over the world. You can learn it...
In this tutorial, we will learn how to perform a slice on thelist. In apythonprogramming language, if we want to access elements from the sequence, we can access them through the index method. The positive index starts from 0. The negative index starts from -1. But what if we want to...
In my opinion, this is the most readable option, and I believe it’s also the most efficient version. In fact, the performance should be similar to the slice. However, Python changes a lot, so the other methods mentioned here may be just as performant—check out my benchmarks below ...

The word[::-1] slice syntax reverses a string. Each element will have reverse_word() applied to it, and the sorting order will be based on the characters in the reversed version of each word. If two words have the same final letter, the next letter is compared, and so on....
