8.1 Slicing Strings

By | September 29, 2021

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.

Example

Get the characters from position 2 to position 5 (not included):
b = “Hello, World!”
print(b[2:5])

Output:
llo

Note: The first character has index 0.

Slice From the Start

By leaving out the start index, the range will start at the first character:

Example

Get the characters from the start to position 5 (not included):
b = “Hello, World!”
print(b[:5])

Output:
Hello

Slice To the End

By leaving out the end index, the range will go to the end:

Example

Get the characters from position 2, and all the way to the end:
b = “Hello, World!”
print(b[2:])

Output:
llo, World!

Negative Indexing

Use negative indexes to start the slice from the end of the string:

Example

Get the characters:

From: “o” in “World!” (position -5)

To, but not included: “d” in “World!” (position -2):
b = “Hello, World!”
print(b[-5:-2])

Output:
orl
