In this example, we define a function calledadd_two_numbersthat takes two parameters:number1andnumber2. The function returns the sum of these two numbers. Step 2: Call the Function Once you have defined the function, you can call it by passing the required arguments. Here’s how you can ...
In this program, we asked the user to enter two numbers and this program displays the sum of two numbers entered by user. We use the built-in function input() to take the input. Since, input() returns a string, we convert the string into number using the float() function. Then, the...

2. Add Two Numbers 两数相加 给出两个非空的链表用来表示两个非负的整数。其中,它们各自的位数是按照逆序的方式存储的,并且它们的每个节点只能存储一位数字。 如果,我们将这两个数相加起来,则会返回一个新的链表来表示它们的和。 您可以假设除了数字 0 之外,这两个数都不会以 0 开头。

You are given two non-empty linked lists representing two non-negative integers. The most significant digit comes first and each of their nodes contain a single digit. Add the two numbers and return it as a linked list. ...
"""Adds two numbers.""" return a + b print(add.__name__) # 输出:"add" print(add.__doc__) # 输出:"Adds two numbers." 在这个例子中,使用functools.wraps(original_function)装饰wrapper函数,确保了原函数add的元信息得到保留。 3.2 无参装饰器的编写与实践 ...
