number1 = float(input("Number1= "))

number2 = float(input("Nnmber2= "))

number3 = float(input("Number3= "))

if number1 >= number2 >= number3:

print("最大值为："，number1)

print("最小值为："，number3)

elif number3 >= number1 >= number2:

print("最大值为："，number3)

print("最小值为："，number2)

elif number1 >= number3 >= number2:

print("最大值为："，number1)

print("最小值为："，number2)

elif number2 >= number1 >= number3:

print("最大值为："，number2)

print("最小值为："，number3)

elif number3 >= number2 >= number1:

print("最大值为："，number3)

print("最小值为："，number1)

print("最大值为："，number2)

print("最小值为："，number1)
