In this article, we would like to show you how to replace last n characters in string in Python.
Quick solution:
text = "ABC"
size = len(text) # text length
n = 2 # number of characters to replace
replacement = "XY" # replace with this
text = text.replace(text[size - n:], replacement)
print("String after: ", text) # AXY
Practical example
In this example, we use replace() method to replace last 2 characters in text string.
text = "ABC"
print("String before:", text)
size = len(text) # text length
n = 2 # number of characters to replace
replacement = "XY" # replace with this
text = text.replace(text[size - n:], replacement)
print("String after: ", text) # AXY
Output:
String before: ABC
String after: AXY
Note:
Number of characters to replace (
n) and number of characters inreplacementdon't have to be the same.
