Python 程序进行算术运算

2024 年 9 月 5 日 | 阅读 3 分钟

算术运算是由计算器执行的，我们可以在其中执行加法、减法、乘法和除法。此示例显示了基本的算术运算，即：

加法
减法
乘法
除法

让我们理解下面的例子。

示例 -

# Simple Python program to understand the arithmetical operator addition
# Here, we are storing the first input numbers in num1  
num1 = input('Enter first number: ')  
# Here, we are storing the second input numbers in num2
num2 = input('Enter second number: ')  
# Here, we are declaring a variable sum to store the result
# Here, we are using the arithmetical operator to add the two numbers  
sum = float(num1) + float(num2)  
# Here, we are printing the sum of the given two numbers 
print('The sum of {0} and {1} is {2}'.format(num1, num2, sum))    

输出

Enter first number: 10
Enter second number: 20
The sum of 10 and 20 is 30.0

解释 -

在上面的代码中，我们使用 input() 函数将用户输入作为整数获取。然后，我们对给定的数字执行算术运算，并使用 print 语句打印结果。我们使用 format() 方法来格式化字符串

示例 1

# Simple Python program to understand the arithmetical operator subtraction
# Here, we are storing the first input numbers in num1  
num1 = input('Enter first number: ')  
# Here, we are storing the second input numbers in num2
num2 = input('Enter second number: ')  
# Here, we are declaring a variable min to store the result
# Here, we are using the arithmetical operator to subtract the two numbers  
min = float(num1) - float(num2)  
# Here, we are printing the subtraction of the given two numbers 
print('The subtraction of {0} and {1} is {2}'.format(num1, num2, min))    

输出

Enter first number: 10
Enter second number: 20
The subtraction of 10 and 20 is -10

示例 2

# Simple Python program to understand the arithmetical operator muitiplication
# Here, we are storing the first input numbers in num1  
num1 = input('Enter first number: ')  
# Here, we are storing the second input numbers in num2
num2 = input('Enter second number: ')  
# Here, we are declaring a variable mul to store the result
# Here, we are using the arithmetical operator to multiply the two numbers  
Mul = float(num1) * float(num2)  
# Here, we are printing the multiplication of the given two numbers 
print('The multiplication of {0} and {1} is {2}'.format(num1, num2, mul))    

输出

Enter first number: 10
Enter second number: 20
The multiplication of 10 and 20 is 200

示例 3

# Simple Python program to understand the arithmetical operator division
# Here, we are storing the first input numbers in num1  
num1 = input('Enter first number: ')  
# Here, we are storing the second input numbers in num2
num2 = input('Enter second number: ')  
# Here, we are declaring a variable div to store the result
# Here, we are using the arithmetical operator to divide the two numbers  
div = float(num1) - float(num2)  
# Here, we are printing the division of the given two numbers 
print('The division of {0} and {1} is {2}'.format(num1, num2, min))    

输出

Enter first number: 10
Enter second number: 20
The division of 10 and 20 is 0.5
