Question

python “TypeError: object() takes no parameters”问题，求大神帮忙看看

calculator.py
class Count:

def __int__(self,a,b):
self.a = int(a)
self.b = int(b)

def add(self):
return self.a + self.b
test.py
from calculator import Count

#测试两个整数相加
class TestCount:

def test_add(self):
try:
j = Count(2,3)
add = j.add()
assert (add == 5),'test'
except AssertionError as msg:
print(msg)
else:
print("Test Pass!")

#执行测试类的测试方法

mytest = TestCount()
mytest.test_add()

错误提示信息：
Traceback (most recent call last):
File "E:\Python_Project\unittest\test.py", line 20, in <module>
mytest.test_add()
File "E:\Python_Project\unittest\test.py", line 8, in test_add
j = Count(2,3)
TypeError: object() takes no parameters

Answer 1

Count这个类的构造方法写错了，写成了

def __int__(self,a,b):

应该是：

def __init__(self,a,b):
