在下面的程序中，三个数字分别存储在 num1、num2 和 num3 中。我们使用 if...elif...else 梯形结构来找出其中最大的并显示出来。
源代码
# Python program to find the largest number among the three input numbers
# change the values of num1, num2 and num3
# for a different result
num1 = 10
num2 = 14
num3 = 12
# uncomment following lines to take three numbers from user
#num1 = float(input("Enter first number: "))
#num2 = float(input("Enter second number: "))
#num3 = float(input("Enter third number: "))
if (num1 >= num2) and (num1 >= num3):
largest = num1
elif (num2 >= num1) and (num2 >= num3):
largest = num2
else:
largest = num3
print("The largest number is", largest)
输出
The largest number is 14
注意：要测试程序，请更改 num1、num2 和 num3 的值。
