You can return a range of characters by using the slice syntax.

April 11, 2020 - The slice function takes in the values of start, stop and step as arguments and returns a slice object. This slice object can then be passed within the square brackets in place of start:stop:step to access the desired slice.

February 1, 2022 - I'm very new to Python and one thing I find confusing and unintuitive is that some things, like slices, start counting at 0 but other things like groups in regular expressions start counting at 1.

The type object for slice objects. This is the same as slice in the Python layer.

>>> +---+---+---+---+ >>> |-4 |-3 |-2 |-1 | <= negative indexes >>> +---+---+---+---+ >>> | A | B | C | D | <= sequence elements >>> +---+---+---+---+ >>> | 0 | 1 | 2 | 3 | <= positive indexes >>> +---+---+---+---+ >>> |<- 0:3:1 ->| <= extent of the slice: "ABCD"[0:3:1]

In Python, a slice is an object that allows you to extract a portion of a sequence, such as a list, tuple, or string.

You can return a range of characters by using the slice syntax. Specify the start index and the end index, separated by a colon, to return a part of the string. Get the characters from position 2 to position 5 (not included): b = "Hello, World!" print(b[2:5]) Try it Yourself » · Python Strings Tutorial String Literals Assigning a String to a Variable Multiline Strings Strings are Arrays Negative Indexing on a String String Length Check In String Format String Escape Characters

How does Python's slice notation work? That is: when I write code like a[x:y:z], a[:], a[::2] etc., how can I understand which elements end up in the slice? See Why are slice and range upper-bound

April 3, 2020 - One of these similarities include the idea of "slicing" some form of data. Slicing does exactly what it implies, it "slices" up data into smaller parts. Every language has their own particular way of doing this. Lets take a look at how Python in particular handles this kind of operation.

September 24, 2023 - You can read more about __getitem__() in The Manor House, the Oak-Panelled Library, the Vending Machine, and Python's `__getitem__()`. In this new class called TestList, which inherits from list, you first print the value and data type of the argument in the __getitem__() method, and then you call the list's __getitem__() method and return its value. This is what super().__getitem__(item) does since list is the superclass for TestList. The syntax 2:7 within the square brackets represents a slice object.

September 17, 2026 - Use Python slice notation to extract substrings and sublists with start, stop, and step indices, including negative indexing and reverse iteration

September 24, 2026 - Python’s slice notation provides a quick way for programmers to extract sections of sequences, such as lists and strings.

August 3, 2026 - In Python, slicing uses colons in square brackets to grab part of a list, string, or tuple: first items, last items, reverse, and step.

December 11, 2025 - In Python, you perform slicing using the colon : operator. The syntax for slicing is as follows: ... where start_index is the index of the first element in the sub-sequence and end_index is the index of the last element in the sub-sequence ...
