Python String – Get last N characters

Python String – Get last N characters

To get the last N characters from a string in Python, you can slice the string with negative start index like start=-N. The stop and step for the slice can be left with default.

Or you can specify a start value of length of string minus N.

In this tutorial, you will learn how to get the last N characters from a string in Python using string slicing, with examples.

1. Get last N characters from string using string slicing in Python

If x is the given string, then use the following expression to get the substring with the last n characters from the original string.

x[-n:]

In the following program, we take a string value in variable x, get the last 4 characters, and print it to output.

# Input string
x = "Hello, World!"

# Number of characters to retrieve
n = 4

# Get the last n characters
last_n_characters = x[-n:]

# Print the result
print(last_n_characters)

Output

If you would like to use positive index while slicing the string, you may use the following expression to get the last N characters from the string in x.

x[len(x)-n:]

# Input string
x = "Hello, World!"

# Number of characters to retrieve
n = 4

# Get the last n characters
last_n_characters = x[len(x) - n:]

# Print the result
print(last_n_characters)

Output
