问题描述

电话意味着什么？如何在Python中调用函数？

What does "call" mean and do? How would you "call" a function in Python?

推荐答案

当你调用一个函数时，你基本上只是告诉程序执行该功能。所以，如果你有一个函数添加了两个数字，例如：

When you "call" a function you are basically just telling the program to execute that function. So if you had a function that added two numbers such as:

def add(a,b):
    return a + b

你可以这样调用函数：

you would call the function like this:

add(3,5)

其中将返回8.在这种情况下，您可以将任何两个数字放在括号中。你也可以调用这样的函数：

which would return 8. You can put any two numbers in the parentheses in this case. You can also call a function like this:

answer = add(4,7)

在这种情况下，将变量答案设置为11。

Which would set the variable answer equal to 11 in this case.
