用python求三个数中最大的奇数，主要用branching语法

#Find the largest odd number among 3 numbers
num1=int(input("请输入第一个数："))
num2=int(input("请输入第二个数："))
num3=int(input("请输入第三个数："))
if num1%2==0 and num2%2==0:
    if num3%2!=0:
        biggest=num3
    else:print("这三个数都不是奇数")
elif num1%2==0 and num2%2!=0:
    if num3%2==0 or num2>num3:
        biggest=num2
    else:biggest=num3
elif num1%2!=0 and num2%2==0:
    if num3%2==0 or num1>num3:
        biggest=num1
    else:biggest=num3
elif num1%2!=0 and num2%2!=0:
    if num3%2!=0:
        biggest=num1
        if biggest<num2:
            biggest=num2
        if biggest<num3:
            biggest=num3
    elif num1>num2:
        biggest=num1
    else:biggest=num2
    print("三个数中最大的奇数为：%s"% biggest)
