当你想从函数中得到一个结果并用这个结果继续在其他地方执行时,可以使用return后紧跟着返回的值。 def add(a, b): return a + b result = add(2, 3) # result 将会得到值 5 1.2不带任何表达式 如果return后面没有任何表达式,那么函数将返回None。None是 Python 中一个特殊的类型,表示没有值。 def do_n...
字典(Dictionary)是另一种重要的数据类型,它由键值对组成,用于存储和操作数据。 本文将介绍如何在Python中使用列表,并将列表作为函数的返回值,其中包含字典。我们将会通过代码示例来演示这个过程,并使用Mermaid语法来绘制关系图和流程图,以帮助读者更好地理解。 列表和字典的基本概念 在开始具体介绍之前,我们先来了解一...

a = x % y b = (x-a) / y return ( a,b ) # 也可以写作 return a, b (c, d )= F1( 9, 4) # 也可以写作 c , d = F1 ( 9, 4 ) print c ,d 结果显示:1, 2 Python与大多数其它语言一样有局部变量和全局变量之分, 但是它没有明显的变量声明。变量通过首次赋值产生, 当超出作用范...
The return value of a Python function can be any Python object. Everything in Python is an object. So, your functions can return numeric values (int, float, and complex values), collections and sequences of objects (list, tuple, dictionary, or set objects), user-defined objects, classes,...
Note: You should never do var = get_mother(), since let us assume var is a dictionary and you iterate by var.items() it will give an error citing None has no method items(). It you intentionally return None then it must be taken care of in the calling function appropriately. Using...

Here's an example of how you can return a dictionary entry as a primitive in Python: ```python def create_dict_entry(key, value): return (key, value) # Example usage: key = "example_key" value = "example_value" entry = create_dict_entry(key, value) print(entry) # Output: ('ex...
Previously, I could get dictionary keys, values, or items of a dictionary very easily as list: PYTHON2.7>>>newdict = {1:0,2:0,3:0}>>>newdict {1:0,2:0,3:0}>>>newdict.keys() [1,2,3] Now, I get something like this in ...
In this example, the function takes aninput_value, multiplies it by 2, and returns a dictionary containing a single key-value pair, where the key is theinput_valueand the value is the computedoutput_value. Download your Python cheat sheet, print it out, and post it to your office wall!
