为什么一直是失败呢？

class animal(object):

    pass dog=animal()cat=animal()

    dog.name="xiaohuang"

    dog.age='1'

    cat.name='xiaohua'

    cat.age='1.5'

    print (dog.name)

    print (dog.age)

    print (cat.name)

    print (cat.age)

    print后面有空格

     print(dog.name)
 print(dog.age)
 print(cat.name)
