在python中，你如何接受整数作为参数？

Question

How do you write a function that accepts integers as parameters?你如何编写一个接受整数作为参数的函数？

I haven't tried anything yet because I have no idea where to start.我还没有尝试任何东西，因为我不知道从哪里开始。

Answer 1

the way you define any function:你定义任何函数的方式：

def f(x):
    '''
    square x
    '''
    return x**2

print(f(4))

Answer 2

def myfunction(myint):
    print("this is an integer " + str(myint))

myfunction(4)

Answer 3

Python keeps track of the types of variables without having to explicitly state the type. Python 会跟踪变量的类型，而无需显式声明类型。

Answer 4

That being said you can use type hints in Python 3:话虽如此，您可以在 Python 3 中使用类型提示：

def f(x: int):
    return x ** 2

In my opinion they are fantastic.在我看来，他们太棒了。
