In my data science project, I had to perform string slicing, where I needed to extract the domain part of the URLs in the dataset. For that, I applied the slicing concepts using Python’s slicing operator. In this tutorial, I have explained string slicing in Python in detail, using sever...
This tutorial demonstrates the unhashable type: 'slice' error in Python and how to fix it. We first discussed the slicing technique in Python. We demonstrated how dictionaries and the reason behind them do not support this technique. The fix involves the use of different functions like items()...
How to Sort a List in Python Without Using the Sort Function Using For Loop in Python Using While Loop in Python Using Slicing in Python Using pop Method in Python Sorting Different Python Data Types Without Using Sort Function Alternative Sorting Methods in Python Eight Advanced Sorting Techniques...
String slicing can accept a third parameter in addition to two index numbers. The third parameter specifies thestride, which refers to how many characters to move forward after the first character is retrieved from the string. So far, we have omitted the stride parameter, and Python defaults to...
While Python doesn't have a built-in method to reverse the string, there are several ways to do it with just a few lines of code. You can use the slicing operator, the reversed() and string.join() methods, reverse the string using a for loop or recursion. Or, you can easily implem...

In short, there are so many different ways to copy a list. In this article alone, we share eight solutions. If you’re looking for something safe, use the copy method (i.e. my_list.copy()). Otherwise, feel free to try slicing (i.e. my_list[:]) or the list constructor (i.e...
In this tutorial, we will review the Python slice notation, and you will learn how to effectively use it. Slicing is used to retrieve a subset of values. The basic slicing technique is to define the starting point, the stopping point, and the step size – also known as stride. ...
# Using slicing to reverse a string my_string = 'Hello, World!' reversed_string = my_string[::-1] print(reversed_string) The [::-1] syntax in the above code tells Python to slice the entire string and step backward by -1, which effectively reverses the string. ...
