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.

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!" ...

July 18, 2026 - Slicing with s[start:stop] asks for a range of positions and always succeeds, returning an empty string in the worst case rather than crashing. Internally, when you write s[start:stop:step], Python builds a slice object — the same object you’d get by calling slice(start, stop, step) directly — and passes it to the string’s __getitem__ method.

September 29, 2025 - Learn how to index and slice strings in Python 3 with step-by-step examples. Master substring extraction, negative indexing, and slice notation.

January 28, 2022 - Python string indexing can also be used to extract a substring from a larger string. This process is referred to as slicing. To use Python to slice a string from a parent string, indicate the range of the slice using a start index and an end index.

October 5, 2026 - You access string elements in Python using indexing with square brackets. You can slice a string in Python by using the syntax string[start:end] to extract a substring.

O(n+k) for slice assignment · Consider the following ASCII graph showing the contents of the “ABCD” string: >>> +---+---+---+---+ >>> |-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] Consider the following example: >>> "ABCD"[0:2] 'AB' It can be read as: get every single one item between indexes 0 and 2 (exclusive).

April 15, 2024 - The default value of the step size is 1, which selects every character. If we change it to 2, the string slice contains every other character within the defined sequence. The step size comes after the ending index and is separated from it by another colon. Thus, the full syntax of string slicing in Python is as follows:

2 weeks ago - The first index is 0. Slicing creates a new string from a range of indices. The original string stays the same. You write a slice with square brackets. Inside, use start:stop:step.

Python String slicing is a way of creating a sub-string from a given string. In this process, we extract a portion or piece of a string. Usually, we use the slice operator "[ : ]" to perform slicing on a Python String.

April 23, 2026 - The step parameter lets you skip characters in a string. It is written as the third value in the slice: [start:stop:step]. For example, if text = "PythonProgramming", you can get every second character using:

... Syntax: Inside of square brackets, use an inclusive start index position separated from an exclusive end index position by a colon · Shortcuts: Omit the start or the end index to slice all the way to the start or end of the string, respectively

September 3, 2026 - If you omit start, slicing begins at index 0. If you omit stop, it goes to the end of the string. If you omit step, the default is 1. Remember that Python indices start at 0. The stop index is exclusive. This means the character at the stop index is not included in the result. # Basic slicing example text = "Hello World" substring = text[0:5] print(substring) # Output: Hello · In this example, we slice from index 0 up to index 5.

The slice() function returns a slice object.

The third parameter specifies the stride, 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 the stride of 1, so that every character between two index numbers is retrieved. Let’s look again at the example above that prints out the substring “Shark”: ... So, a stride of 1 will take in every character between two index numbers of a slice.
