我正在通过艰难的方式学习python来学习编码，最近我第一次陷入困境。对于这个练习，我们应该编写自己的游戏。我这样做了，但是由于某种原因，每当我运行它时，right_room() 函数都会在我输入答案后退出，而不是继续到下一个房间。任何帮助将不胜感激。这是我的代码：
from sys import exit
def bear_room():
print "You are in a room with a bear."
print "You have two choices. left or right?"
next = raw_input("> ")
if next == "left":
left_room()
elif next == "right":
right_room()
else:
print "No idea what that means..."
def left_room():
print "You went left."
print "There are two doors. right or straight"
next = raw_input("> ")
if next == "right":
bear_room()
elif next == "straight":
second_left()
else:
print "What are you saying, bro?"
def second_left():
print "You went straight."
print "You again have two choices. straight or right?"
next = raw_input("> ")
if next == "straight":
print "You won! Congrats."
exit(0)
elif next == "right":
dead("You opened the door and walked off a cliff. Goodbye!")
else:
print "I didn't quite catch that."
def right_room():
print "You went right."
print "There are two doors. straight or right?"
next == raw_input("> ")
if next == "right":
dead("Oops, a tiger just ate you")
elif next == "straight":
second_right()
else:
"What?!?!?!"
def second_right():
print "You went straight"
print "Nice choice."
print "You have two choices: left or straight"
next == raw_input("> ")
if next == "left":
dead("You just fell 1 million feet to your death.")
elif next == "straight":
print "You made it out alive!"
exit(0)
else:
"WTF?"
def dead(reason):
print reason, "good job!"
exit(0)
def start():
print "You are about to enter a room."
bear_room()
start()
