The assert keyword is used when debugging code.
The assert keyword lets you test if a condition in your code returns True, if not, the program will raise an AssertionError.
You can write a message to be written if the code returns False, check the example below.
assert word.endswith(suffix), "Given word doesn't end with given suffix"
