A slice object is used to specify how to slice a sequence. You can specify where to start the slicing, and where to end. You can also specify the step, which allows you to e.g. slice only every other item.

To use slice notation with a sequence that supports it, you must include at least one colon in the square brackets that follow the sequence (which actually implement the __getitem__ method of the sequence, according to the Python data model.) Slice notation works like this: sequence[start:stop:step]

Mar 8, 2025 · Python list slicing is fundamental concept that let us easily access specific elements in a list. In this article, we’ll learn the syntax and how to use both positive and negative indexing for slicing with examples.

May 9, 2023 · The first slice function is slicing the string to the 2nd index, the second slice function is used to slice the string to the 4th index with a leaving 2nd index. Finally, we are printing both sliced strings in the terminal.

Dec 8, 2022 · In this article, we've briefly looked at how to declare arrays in Python, how to access values in an array, and also how to cut – or slice – a part of an array using a colon and square brackets. We also learned how slicing works …

A guide to slicing Python lists/arrays and Tuples, using multiple forms of syntax. We can use the short form of Python slicing, or the slice method.

In this tutorial, we will learn to use Python slice () function in detail with the help of examples.

Jan 28, 2025 · In Python, slice() is used to access a portion of a sequence such as a list or tuple. It helps improve code readability and maintainability by giving meaningful names to slices instead of using hardcoded indices.

Positive values slice the list from the first element to the last element while negative values slice the list from the last element to the first element. In addition to extracting a sublist, you can use the list slice to change the list such as updating, resizing, and deleting a part of the list.

Summary: in this tutorial, you’ll learn about Python slicing and how to use it to extract data from and assign data to a sequence. So far you’ve learned about slicing such as list slicing. Technically, slicing relies on indexing. Therefore, slicing only works with sequence types.
