To find and remove the last occurrence of a specific substring in a string, you can use the str.rfind() method to find the position of the last occurrence and then slice the string accordingly. Here’s a function that does this:
def remove_last_occurrence(text, substring):
index = text.rfind(substring)
if index == -1: # substring not found
return text
# Remove the substring
return text[:index] + text[index + len(substring):]
text = "I have a cat. The cat is cute. I love my cat."
substring = "cat"
result = remove_last_occurrence(text, substring)
print(result)
This script will output:
I have a cat. The cat is cute. I love my .
The last occurrence of the substring “cat” has been removed from the original string.
