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

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)

String before: ABCD
String after: AXYZ
Note:
Number of characters to replace (
3) and number of characters inreplacementdon't have to be the same.
