python 数字加法运算

Take input of two numbers from the user and print their sum.

从用户那里输入两个数字并打印它们的总和。

Example:

例：

    Input:
A = 2, B = 3
Output:
Sum = 5

Here, we are implementing the program to find the addition of two numbers using 4 different ways.

在这里，我们正在实施程序，以使用4种不同的方法来找到两个数字的加法 。

1) Simply take input from the user and typecast to an integer at the same time after that performing addition operation on the both number.

1)只需从用户输入并在对两个数字进行加法运算后同时将其类型转换为整数 。

if __name__ == "__main__" :
# take input from user
a = int(input())
b = int(input())
# addition operation perform
sum_num = a + b
print("sum of two number is: ",sum_num)

Output

输出量

10
20
sum of two number is:  30

2) Using a user-defined function for doing the sum of two numbers.

2)使用用户定义的函数进行两个数字的和。

# define a function for performing
# addition of number
def sum_num(a,b) :
return a + b
# Main code
if __name__ == "__main__" :
a = int(input())
b = int(input())
print("sum of two number:",sum_num(a,b))

Output

输出量

10
20
sum of two number: 30

3) We are taking the input from user in one line after that typecast into an integer and stored them in the list then use sum() inbuilt function which returns the sum of elements of the list.

3)在类型转换后，我们将用户输入的内容输入一行以整数形式存储，然后将其存储在列表中，然后使用sum()内置函数返回列表元素的总和。

if __name__ == "__main__" :
# take input from the user in list
a = list(map(int,input().split()))
# sum function return sum of elements
# present in the list
print("sum of two number is:",sum(a))

Output

输出量

10 20
sum of two number is: 30

4) We are taking the input from user in one line and store them in two different variables then typecast both into an integer at the time of addition operation.

4)我们将用户的输入放在一行中，并将它们存储在两个不同的变量中，然后在加法运算时将它们都转换为整数 。

if __name__ == "__main__" :
# take input from the user in a and b variables
a,b = input().split()
# perform addition operation
rslt = int(a) + int(b)
print("sum of two number is:",rslt)

Output

输出量

10 20
sum of two number is: 30
