In this article, we would like to show you how to replace last 3 characters in string in Python.

Quick solution:

text = "ABCD"

size = len(text)     # text length
replacement = "XYZ"  # replace with this

text = text.replace(text[size - 3:], replacement)

print(text)  # AXYZ

 

Practical example

In this example, we use replace() method to replace last 3 characters in text string.

text = "ABCD"

print("String before:", text)

size = len(text)     # text length
replacement = "XYZ"  # replace with this

text = text.replace(text[size - 3:], replacement)

print("String after: ", text)  # AXYZ

Output:

String before: ABCD
String after:  AXYZ

Note:

Number of characters to replace (3) and number of characters in replacement don't have to be the same.
