Today, we’re going to learn how to clone or copy a list in Python. Unlike most articles in this series, there are actually quite a few options—some better than others. In short, there are so many different ways to copy a list. In this article alone, we share eight solutions. If ...
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...
We have so many different ways to do this slice indexing we will see an example of each one in the next section. Points to remember while working with the numPy in python; NumPy provides us with faster accessing of array elements in comparison to the list. ...
Thus, it slices the year and day part of each date in the list and prints it using‘print(f”Year: {year}, Day: {day}”)’. This is how you can perform slicing in Python string using the slice() function. Conclusion In this Python tutorial, you learned how to dostring slicing in...
The str() function can convert the whole list, including its structure, into a string format. This is particularly useful for logging or displaying the list as is. It also works regardless of the data types of the elements in a list. # List of strings str_list = ["Python", "is", ...
Python >>>importre>>>shopping_list="Apple:Orange|Lemon-Date">>>re.split(r"[:|-]",shopping_list)['Apple', 'Orange', 'Lemon', 'Date'] In this example, the regular expression[:|-]specifies that Python should split the string at any occurrence of a colon, vertical bar, or minus sig...

Finally, the two tabs—tab1 and tab2—have mirrored local history, as they share the same list object under the hood. Ultimately, how you implement shallow and deep copying in custom classes is entirely up to you. Additionally, if you’re using Python 3.13 or later, then you might also...
