Question

The replace_ending function replaces the old string in a sentence with the new string, but only if the sentence ends with the old string. If there is more than one occurrence of the old string in the sentence, only the one at the end is replaced, not all of them. For example, replace_ending("abcabc", "abc", "xyz") should return abcxyz, not xyzxyz or xyzabc. The string comparison is case-sensitive, so replace_ending("abcabc", "ABC", "xyz") should return abcabc (no changes made). 1 point

Answer 2

Answer:

def replace_ending(sentence, old, new):

# Check if the old string is at the end of the sentence  

if sentence.endswith(old):

 # Using i as the slicing index, combine the part

 # of the sentence up to the matched string at the  

 # end with the new string

 i = len(old)

 new_sentence = sentence[:-i]+new

 return new_sentence

# Return the original sentence if there is no match  

return sentence
