有人能告訴我這個 python 代碼有什么問題嗎？ 我是新手，一直在嘗試運行它：

legs = input('Number of legs he have?\n')
def Dance(legs):
    if legs = 'Two':
        print('HE HAVE TWO LEGS SO HE CAN  DANCE')
    elif legs:
        print('HE HAVE ONE LEG AND HE CAN DO SOMETHING')
    else:
        print('NO LEGS SO HE CANT DANCE')

Answer 1

需要調用 function。 嘗試這個：

legs = int(input('Number of legs he have?\n'))
def Dance(legs):
    if legs == 2:
        print('HE HAVE TWO LEGS SO HE CAN  DANCE')
    elif legs == 1:
        print('HE HAVE ONE LEG AND HE CAN DO SOMETHING')
    else:
        print('NO LEGS SO HE CANT DANCE')

Dance(legs) # this invokes/calls the function

Answer 2

另一種方法是將 input 語句放在 function 中，這樣更簡潔：

def Dance():
    legs = input('Number of legs he has?\n')
    if legs == 'Two':
        print('HE HAS TWO LEGS SO HE CAN  DANCE')
    elif legs == 'One':
        print('HE HAS ONE LEG AND HE CAN DO SOMETHING')
    elif legs == 'Zero':
        print('NO LEGS SO HE CANNOT DANCE')
    else:
        print('I do not understand your input')

Dance()   #this invokes/calls the function

Output：

Number of legs he has?
 One
HE HAS ONE LEG AND HE CAN DO SOMETHING
