Sorry for my bad english. I try to use doctest to verify my function raise some exception. But in fact the exception is correctly raise but my test dont pass despite the same exception is raise on the test. I use python 3.10.4
>>> add_integer = __import__('0-add_integer').add_integer
>>> add_integer(1, 2)
3
>>> add_integer(100, -2)
98
>>> add_integer(2)
100
>>> add_integer(100.3, -2)
98
>>> add_integer(4, "School")
Taceback (most recent call last):
...
TypeError: b must be an integer
>>> add_integer(None)
Taceback (most recent call last):
...
TypeError: a must be an integer
function to test
#!/usr/bin/python3
"""

def add_integer(a, b=98):

if type(a) not in [int, float]:
raise TypeError("a must be an integer")
if type(b) not in [int, float]:
raise TypeError("b must be an integer")
return int(a) + int(b)
but i still having a bad output
