Development - Beginner, exercise 29

Text

Write down a small function in Python that takes in input two strings and returns True if they are identical, False if they are not identical but contains the same number of characters, otherwise it returns the shorter one.

Solution

# Test case for the function
def test_f(s, t, expected):
    result = f(s, t)
    if expected == result:
        return True
    else:
        return False


# Code of the function
def f(s, t):
    if s == t:
        return True
    elif len(s) == len(t):
        return False
    elif len(s) < len(t):
        return s
    else:
        return t


# Tests
print(test_f("ciao", "ciao", True))
print(test_f("ciao", "oaic", False))
print(test_f("ciao", "me", "me"))
print(test_f("me", "ciao", "me"))
