我正在通过创建基于文本的冒险游戏来学习Python。我很难确定是否可以调用先前的变量。例如，这是我的代码段（有关如何整合的建议会有所帮助哈哈），我有一条if语句，允许播放器选择输入。
在ALIEN输入下，您将看到他们是否选择1。他们选择“接受失败”。
在此代码结尾处，我有相同的结果，以便玩家在IMPROV输入后再次选择“接受失败”。如果选择了该选项，我想循环回到第一个外来变量。如果省略，而不是再次写相同的语句。这可能吗？

答案 0 :(得分：2)
您似乎根本没有使用功能。那是你应该做的事情：）
例如，不要每次都重复输入颜色，而使用colored_input：
def colored_input():
return input(Fore.YELLOW + Style.BRIGHT + "> ")
alien = colored_input()
第二，我将合并“事件”，而不是像您一样键入它们。例如，我会将页面分别存储在一个元组中。像这样：
STARTING_TEXT = """
Theres an alien eating what appears to be a human arm, though its so damaged it's hard to be sure. There is a knife next to the alien.
what do you want to do?¨
"""
STARTING_CHOICES = """
Go for the knife
Attack alien before it notices you
"""
EVENT_START = (STARTING_TEXT, STARTING_CHOICES)
三引号会创建多行字符串。请注意，第一和最后一个换行符是字符串的一部分，因此稍后您将不得不删除它。
当然，您可以将文本直接放入元组：
EVENT_APPROACH_KNIFE = ("""
You approach the knife slowly, While the alien is distracted. You finally reach the knife, but as you look up, the alien stares back at you.
You make a move to stab the alien, but he is too quick. With one swift motion, the alien thrusts you into the air.
You land hard, as the alien makes it's way towards you again. What should you do?
""", """
Accept defeat?
Last ditch effort?
""")
现在，如果您有一堆这样的“事件”，则可以在同一步骤中显示它们并要求输入：
def run_event(event): # from here on, the "event" variable will be whichever EVENT_* you call
text, choices = event # separates the two items of the tuple
# Remove whitespace from start and end. This gets rid of the starting and ending newline
# that I mentioned earlier:
# (go ahead, remove the following line and see what happens)
text = text.strip()
# Now let's get individual lines - split the text on newlines:
text_lines = text.split("\n")
# print them with colors:
for line in text_lines:
print(Fore.YELLOW + line)
print() # To print an empty line, you don't even need to add the ""
# now let's do the same with choices:
choices = choices.strip()
choice_lines = choices.split("\n")
for num, line in enumerate(choice_lines):
# the "enumerate" gives you "num" as the number of the line
# but it counts from 0, so we need to add 1
# (and wrap it in str() because otherwise you can't add it to a string
print(Fore.GREEN + Style.BRIGHT + str(num + 1) + ". " + line)
print()
# finally, ask for player's choice and return it
return colored_input()
这将大大简化您的代码。假设您事先定义了所有事件，则可以执行以下操作：
door = run_event(EVENT_DOOR)
if door == "1":
alien = run_event(EVENT_ALIEN)
if alien == "1":
improv = run_event(EVENT_IMPROV)
...
elif alien == "2":
...
您可以对此进行进一步开发，例如，对选择使用列表而不是多行字符串，并将事件与选择相关联。
但是，要回答您的原始问题：像这样构造，您可以将游戏的各个部分变成功能。像这样：
def accept_defeat():
improv = run_event(EVENT_ACCEPT_DEFEAT)
if improv == "1":
...
elif improv == "2":
wall = run_event(EVENT_LAST_DITCH)
if wall == "1":
accept_defeat() # here you're calling the same function again!
elif ...:
...
# and then somewhere in the main function:
def main():
alien = run_event(EVENT_ALIEN):
if alien == "1":
accept_defeat()
elif ...:
...
从同一函数中调用函数时，您正在使用递归。实际上，这是一个非常糟糕的解决方案：对于一个实例，如果您决定连续“接受失败”超过128次左右，则会超出递归限制，并且您的程序将崩溃。
但是要避免递归，您将不得不以更深层次的方式重新编写程序。在您的技能水平上达到ISTM，此解决方案可以正常工作。当您达到这种方法的极限时，或者当您觉得自己很了解此代码并且想要更多挑战时，您可以学到更多：）
答案 1 :(得分：0)
我建议制作一种图形。您必须确定所有选项，但您可能已经必须这样做。此外，实施循环将有助于处理不可接受的答案。
一种可行的可能性（测试here，仅供参考，它甚至不如OP示例完整，但您可以输入两次以查看其运行情况）：
# make a class for each event, it'll contain a description and any number of choices
class Event:
def __init__(self,description,choices,options):
self.description=description
self.choices=choices
# options should be a list the same length as choices with corresponding keys to other events
self.options=options
def to_string(self):
print(self.description+'\n')
for choice in self.choices:
print(choice+'\n')
# point to the next event
return self.options[self.make_choice()-1]
def make_choice(self):
c=0
# this won't allow a user to enter a value not offered
while c<1 or c>len(self.choices):
c=int(input("your choice> "))
return c
# this is your map
