filter(function or None, iterable) --> filter object Return an iterator yielding those items of iterable for which function(item) is true. If function is None, return the items that are true. """ 翻译:如果函数里面每个对象都是True,返回一个可迭代对象的生成器。如果函数为空,这返回对象里面每个...
关键字可变参数：允许传入不定数量的关键字参数，在函数内部以字典（dictionary）的形式进行处理。函数返回值 函数可以返回一个值或多个值。使用 `return` 关键字返回值，并可以使用元组（tuple）返回多个值，也可以返回列表、字典等。示例代码如下：def add_numbers(a, b):(tab)return a + bresult = add_numbers...

In general, a function takes arguments (if any), performs some operations, and returns a value (or object). The value that a function returns to the caller is generally known as the function’s return value. All Python functions have a return value, either explicit or implicit. You’ll ...

嵌套函数 Nested Function,也是函数作为对象的体现。嵌套函数的两种表现: 1,在一个函数定义的内部,嵌套地给出另一个函数定义。 2,函数名称所代表的函数对象(通常是内部函数或者全局函数),可以作为返回值,即 在函数的 return 语句中返回的是一个函数对象。 注意:如果,只返回函数名,那么就是返回了这个函数对象的地址...
