代码举例-01

num1 = 15
num2 = 12

sum = num1 + num2 

print("Sum of {0} and {1} is {2}" .format(num1, num2, sum)) 

输出结果：

Sum of 15 and 12 is 27

代码举例-02

number1 = input("First number: ") 
number2 = input("\nSecond number: ") 

sum = float(number1) + float(number2) 

print("The sum of {0} and {1} is {2}" .format(number1, number2, sum)) 

输出结果为：

First number: 13.5 Second number: 1.54
The sum of 13.5 and 1.54 is 15.04
