Since return_42() returns a numeric value, you can use that value in a math expression or any other kind of expression in which the value has a logical or coherent meaning. This is how a caller code can take ad
executing. In other words, we can say that the return statement is the last statement that a function or method executes before it terminates. We can even return a function from another function. A function without a return statement or a return statement without a value returns None by ...

A return statement with no argument is equivalent to a return none statement. The syntax for defining a function in Python: def function_name(arg1, arg2, … argN): return value Example: Python 1 2 3 4 5 6 7 8 9 10 # Defining a function to display course details def course...
print(f"{user_input}的意思是:{meaning}") 代码中,我们使用一个无限循环来不断接收用户输入。如果用户输入了"q",循环会结束,程序退出。否则,我们会调用lookup_word()函数来查找输入单词的意思,并将结果打印出来。 通过这个实例,我们可以学习如何使用字典来存储和查找数据,并了解如何编写一个简单的用户界面来与用...

在函数中使用return关键字能够进行返回值,下方我们定义了一个函数,它的作用计算两个数字的和,我们不在意它的计算过程,我们重视的是这个函数的结果,所以我们让这个函数将最后的计算结果返回: """ def 函数名(参数): 用参数做点事 做多一些事 告诉我结果 ...
The word "return" is also often used to describe the result of an expression thatisn'ta function call. For example, "2 + 3returns5". Every function has a "return value" in Python. The default return value isNone. Decorator Decorators augment the behavior offunctionsandclasses. Decorators ...
