作为python开发,"func"和"func()"有什么区别?


在Python中,"func"和"func()"的区别主要在于它们是否立即执行函数。 1. "func":在Python中,如果你只是定义了一个函数,而没有调用它,那么这个函数就不会执行。当你在定义函数时使用"func",那么你只是定义了一个函数,但没有调用它。例如: ```python def func(): print("Hello, World!") func ``` 在这个例子中,"func"只是一个函数的定义,它并没有被执行。 2. "func()":当你在定义函数后立即调用它时,你可以使用"func()"。当你使用"func()"时,Python会立即执行函数体中的代码。例如: ```python def func(): print("Hello, World!") func() ``` 在这个例子中,当你运行这段代码时,Python会立即执行"func()"中的代码,输出"Hello, World!"。 来说,"func"和"func()"的主要区别在于是否立即执行函数。"func"只是定义了一个函数,而"func()"会立即执行函数体中的代码。 [2023-11-08 00:48:15 | AI写代码神器 | 229点数解答]
