当我问用户他们想使用该程序的对象时,忽略了elif语句。
from __future__ import print_function
import random
#Variables
name = raw_input
answer = raw_input
objectList = ['coin', 'piece of paper', 'bundle of sticks']
#Game code
def game():
name = raw_input("What is your name?: ")
print ('-----------------------------------------------------------------')
print ('Hello, ' + str(name) + ', you tripped into a hole and fell unconcious')
print ('to wake up in a dungeon. There is a door in front of you, but it ')
print ('seems to be locked.')
print ("\n")
print ('Look around for a tool?')
askForObject()
#answer for question
def askForObject():
if "yes" in answer():
print('-----------------------------------------------------------------')
print('There are two objects on the ground; a mysterious contraption with')
print('two prongs, and a ' + random.choice(objectList) + '.')
print("\n")
print('Which tool will you pick up? The contraption or the object?')
pickUpPrompt()
else:
print('What do you mean? Yes, or no?')
askForObject()
#ask the user what tool they will pick up
def pickUpPrompt():
if 'object' in answer():
print('You picked up the object, but it has no apparent use on the door')
print('Try again')
pickUpPrompt()
elif 'contraption' in answer():
print('You picked up the contraption.')
doorPrompt()
else:
print('What object are you talking about?')
pickUpPrompt()
def doorPrompt():
print ('-----------------------------------------------------------------')
print ('Will you use the contraption on the door?')
if 'yes' in answer():
print ('door')
game()
我尝试使用其他运算符代替,但是在如何调用字符串方面遇到了问题。如果您两次输入相同的答案似乎很有效,但我不知道为什么。
elif不能正常工作,因为它第二次调用了raw_input。这就是为什么两次输入相同答案的原因,因为第二项符合elif条件。您可以做的是在pickUpPrompt的第一行中调用raw_input并将其保存为变量,然后使用if / elif / else。
def pickUpPrompt():
ans = answer()
if 'object' in ans:
print('You picked up the object, but it has no apparent use on the door')
print('Try again')
pickUpPrompt()
elif 'contraption' in ans:
print('You picked up the contraption.')
doorPrompt()
else:
print('What object are you talking about?')
pickUpPrompt()
