奇数的Python逻辑测试

Question

请问我下面的回答是否正确可行或者有什么改进的地方谢谢。 问题:检查 x y 和 z 是否为奇数或偶数的程序检查数字是否是所有三个中最大的。 在我的回答下方:

    x = 4
    y = 7
    z = 9

  #first condition where 3 numbers are all odd.

    if x%2 == 1 and y%2 == 1 and z%2 == 1:
        if x > y and x > z:
            print "x is the biggest odd number."
        elif x > y and z > x:
            print "z is the biggest odd number."
        else:
            print "y is the biggest odd number."

#second condition where 2 of the numbers are odd
elif x%2 == 0 and y%2 == 1 and z%2 == 1:
    if y > z:
        print "y is the biggest odd number."
    else:
        print "y is the biggest odd number."
elif x%2 == 1 and y%2 == 0 and z%2 == 1:
    if x > z:
        print "x is the biggest odd number."
    else:
        print "z is the biggest odd number."

elif x%2 == 1 and y%2 == 1 and z%2 == 0:
    if x > y:
        print "x is the biggest odd number."
    else:
        print "y is the biggest odd number."    

#third condition where only one of the numbers is odd.

elif x%2 == 0 and y%2 == 0 and z%2 == 1:
    print "z is the biggest odd number."
elif x%2 == 1 and y%2 == 0 and z%2 == 0:
    print "x is the biggest odd number."
elif x%2 == 0 and y%2 == 1 and z%2 == 0:
    print "y is the biggest odd number."

#last condition if none of the numer are odd or not numbers.

else:
    print " None of the numbers are odd or not a number."

Answer 1

哇!那是一大堆代码。为什么不直接将 x,y,z 放入列表中。使用列表理解删除偶数。然后使用 max 函数选择最大值。像这样

arr = [x,y,z]
arr = [i for i in arr if i%2!=0] #select only odd numbers
print(max(arr)) #display the maximum number

然后您可以使用max(arr) 找出包含最大奇数的变量。
