各位大神，我是python小白，在学习中写了一个练习题，代码如下：
class User():
    def __int__(self,first_name,last_name):
        self.first_name = first_name
        self.last_name = last_name
        # self.sex = sex
        # self.age = age
    def describe_user(self):
        print("My name is ",self.first_name,' ',self.last_name)
    def greet_user(self):
        print(self.first_name,self.last_name," welcome you.")
mike6 = User("zhaohua","gov")
mike6.describe_user()

运行

D:\PycharmProjects\Test2\venv\Scripts\python.exe D:/PycharmProjects/Test2/zuoye9-3.py
Traceback (most recent call last):
  File "D:/PycharmProjects/Test2/zuoye9-3.py", line 11, in <module>
    mike6 = User("zhaohua","gov")
TypeError: User() takes no arguments

Process finished with exit code 1


可是我实在找不到毛病在哪里？
求助各位大神帮忙看看，我写了几个例子都没有问题，就这一个有问题。
