判断三个数字中的最大值

判断三个数字中的最大值

方法一：
 1 num1=int(input("num1:"))
 2 num2=int(input("num2:"))
 3 num3=int(input("num3:"))
 4 if num1>num2 and num2>num3:
 5     print(num1)
 6 elif num1>num3 and num3>num2:
 7     print(num1)
 8 elif num2>num1 and num1>num3:
 9     print(num2)
10 elif num2>num3 and num3>num1:
11     print(num2)
12 elif num3>num1 and num1>num2:
13     print(num3)
14 else:
15     print(num3)

方法二：
 1 num1=int(input("num1:"))
 2 num2=int(input("num2:"))
 3 num3=int(input("num3:"))
 4 max_num=20
 5 if num1>num2:
 6     max_num=num1
 7     if max_num>num3:
 8         print("Max Num is",max_num)
 9     else:
10         print("Max Num is",num3)
11 else:
12     max_num=num2
13     if max_num>num3:
14         print("Max Num is",max_num)
15     else:
16         print("Max Num is",num3)
