我对Python 3.5.1中的.find()函数有一个简单的问题
我有一个孤立的情况，它不能在特定的if循环中工作，而且代码就在下面：
import random
import time
import sys
names = ["Bob", "Melissa", "Frank", "Mary", "John", "Denise", "Mark", "Holly"]
x = len(names)-1
randomNameGeneration = names[random.randint(0,x)]
favColors = ["blue","red","green","pink","yellow","purple","black"\
, "gold", "white", "silver", "orange"]
y = len(favColors)-1
randomColorGeneration = favColors[random.randint(0,y)]
endingList = []
# Stats =============================================================
money = 100
health = 100
stamina = 100
sanity = 100
infection = 0
speed = random.randint(4,18)
attack = random.randint(4,18)
defense = random.randint(4,18)
aim = random.random()
charisma = random.randint(4,18)
intelligence = random.randint(4,18)
wisdom = random.randint(4,18)
inventory = []
# Functions =========================================================

global line
line = linenum
# Code for gameplay =================================================

exitShop = True
else:
print("[You sit on a bench outside of the mall]")
time.sleep(2)
else:
print("That's fine with me!")
print("Ending Got: Peaceful Cafe")
sys.exit()
问题发生在商店循环中，每当我选择一个选项时，它都会返回

答案 0 :(得分：3)
您正在为函数分配choiceShopOne，而不是调用该函数。您想要input().lower()而不是input().lower。您使用choiceShopTwo和choiceShopThree犯了同样的错误。
在Python中，str.lower是一种方法，而不是一种属性。您需要使用括号调用方法：str.lower()而不是str.lower。
