Final answer:
Modify the function by adding an elif statement to handle when 'b' is longer and an else statement to return None when 'a' and 'b' are of equal length.
Step-by-step explanation:
The correct answer is to modify the given function so that it can return None when the string lengths of a and b are the same.
The original function only evaluates which string is longer and returns it, but does not handle the case when both strings are of equal length. The updated function should have an additional condition to check for this scenario:
def longer(a: str, b: str):
if len(a) > len(b):
return a
elif len(a) < len(b):
return b
else:
return None
By adding an elif statement to handle the case where b is longer than a, and an else to return None when both strings are equal in length, the function now behaves as intended, covering all possible comparisons.
The correct answer is option Computers and Technology.
The given function is designed to return the longer string between two input strings a and b. However, it does not handle the case where the lengths of a and b are equal. To make the function return None if the lengths of a and b are the same, you can modify the code like this:
def longer(a: str, b: str): if len(a) > len(b): return a elif len(b) > len(a): return b else: return None
In this modified version, an if-elif-else statement is used to check the lengths of a and b and return the appropriate value.
