我已经在python中完成了我的文本游戏。但是，我唯一的问题是，当我输入去哪里时，它不会去那个地方。它在开始的地方而不是用户输入的内容......我没有看到我的if和elif语句有任何问题但是不知道问题出在哪里...事实上我是-did所有elif和if语句但仍然有同样的问题......

答案 0 :(得分：1)
您正在转换输入的文本.lower()，并将其与其中包含大写的文本进行比较 - 这不起作用。修复如下：
if way_picked.lower() == "shop 1":
shop1()
elif way_picked.lower() == "field":
field()
elif way_picked.lower() == "shop":
shop()
elif way_picked.lower() == "house":
house()
elif way_picked.lower() == "farm":
farm()
elif way_picked.lower() == "dead end":
deadend()
elif way_picked.lower() == "field 1":
field1()
哪里。您可能还想使用.strip()来确保在比较它们之前删除引导/训练空格。
另外：请阅读：How to debug small programs (#1)以获取有关如何调试自己的程序的提示，以便更快地找到自己的错误，然后在SO上发布。
一种解决方案是制作一个可以比较的小功能：
def comp(textIn, myOption):
"""Returns True if textIn.strip().lower() equals myOption.strip().lower()"""
return textIn.strip().lower() == myOption.strip().lower()
# The starting point of the game.
def start():
print(" You are at the start of the game MILK ")
print("Now you will have to use the map to navigate around the farm to find the almighty, godly, delicious MILK!!!!")
way_picked = input("Do you want to go to the Shop 1, Field , Shop , House , Farm , Dead end, Shop 1, Field 1 ???? > ")
# This is where the user picks where they want to go within the game.
if comp(way_picked,"Shop 1"):
shop1()
elif comp(way_picked,"Field"):
field()
elif comp(way_picked, "Shop"):
shop()
# etcerea ....
函数comp(userInput,"option")将负责剥离＆amp;降低和比较，只需返回True/False
编辑：处理此问题的其他方法：创建包含密钥（用户输入）的字典和要调用的函数（作为值）：
def func1():
print("F1")
def func2():
print("F2")
def func3():
print("F3")
def func4():
print("F4")
# function are first class citizens in python, you can store them as
# value (without parentheses) to be called later
options = { "f1" : func1, "f2" : func2, "f3" : func3, "f4" : func4}
while True:
userInput = input("F1 to F4:\n\t").strip().lower() # make input trimmed and lower
if userInput in options:
options[userInput] () # execute the stored function (use value + () to execute)
else:
print("\nWrong input!\n")
