我现在在写一个文本冒险风格的游戏，想练习一些if/elif语句。现在遇到了一个关于如何退出if/elif结构的问题。我想让它从最初的if/elif语句继续执行，也就是从最初的elif语句所在的位置往后继续（代码的最后两行）。有可能做到吗？这是我目前的思路：

cave_or_jungle = input("Do you go into the JUNGLE or the CAVE?").lower()

if cave_or_jungle == "cave":
    print("You go into the cave! The cave is cold and dark. You find a rusty lantern and hear strange growling deeper inside.")
    deeper_or_leave = input("Do you go DEEPER or LEAVE?").lower()

    if deeper_or_leave == "deeper":
        print("Deep in the cave, a giant beast jumps out of the darkness.")
        fight_or_run = input("Do you FIGHT or RUN?").lower()

        if fight_or_run == "fight":
            print("The beast is too powerful. You are defeated.")
            print("GAME OVER")
            # Game ends
        elif fight_or_run == "run":
            print("You run back outside and follow the jungle path.")
            # Exit statement here to continue onto line 47 below. Code now runs up to this statement and then stops.
    elif deeper_or_leave == "leave":
        print("You go back outside.")
        # Exit statement here to continue onto line 47 below. Code now runs up to this statement and then stops.
elif cave_or_jungle == "jungle":
    print("You are in the jungle!")
    print("The jungle is thick and noisy. You hear water nearby and see smoke rising through the trees.")
    input("Do you follow the RIVER or the SMOKE?")
    # Have previous two elif statements run to this elif statement and progress with story.

解决方案

你可以用一个循环来解决这个问题：只要游戏还没结束，就检查当前所在的位置并执行相应的分支。break 终止循环，而 continue “重新开始” 循环：

cave_or_jungle = input("Do you go into the JUNGLE or the CAVE?").lower()

while True:
    if cave_or_jungle == "cave":
        print("You go into the cave! The cave is cold and dark. You find a rusty lantern and hear strange growling deeper inside.")
        deeper_or_leave = input("Do you go DEEPER or LEAVE?").lower()

        if deeper_or_leave == "deeper":
            print("Deep in the cave, a giant beast jumps out of the darkness.")
            fight_or_run = input("Do you FIGHT or RUN?").lower()

            if fight_or_run == "fight":
                print("The beast is too powerful. You are defeated.")
                print("GAME OVER")
                # Game ends
                break
            elif fight_or_run == "run":
                print("You run back outside and follow the jungle path.")
                cave_or_jungle = "jungle"
                # skip rest of loop and start from top
                continue
        elif deeper_or_leave == "leave":
            print("You go back outside.")
            cave_or_jungle = "jungle"
            # skip rest of loop and start from top
            continue
    elif cave_or_jungle == "jungle":
        print("You are in the jungle!")
        print("The jungle is thick and noisy. You hear water nearby and see  smoke rising through the trees.")
        input("Do you follow the RIVER or the SMOKE?")
        # Have previous two elif statements run to this elif statement and progress with story.

在Python 3.10及更高版本，你也许可以考虑使用 match 语句。它对循环本身不会有任何影响，但会让重复的条件判断稍微简单一些：

cave_or_jungle = input("Do you go into the JUNGLE or the CAVE?").lower()

while True:
  match cave_or_jungle:
    case "cave":
      print("You go into the cave! The cave is cold and dark. You find a rusty lantern and hear strange growling deeper inside.")
      deeper_or_leave = input("Do you go DEEPER or LEAVE?").lower()

      match deeper_or_leave:
        case "deeper":
          print("Deep in the cave, a giant beast jumps out of the darkness.")
          fight_or_run = input("Do you FIGHT or RUN?").lower()

          match fight_or_run:
            case "fight":
              print("The beast is too powerful. You are defeated.")
              print("GAME OVER")
              # Game ends
              break
            case "run":
              print("You run back outside and follow the jungle path.")
              cave_or_jungle = "jungle"
              # skip rest of loop and start from top
              continue
        case "leave":
          print("You go back outside.")
          cave_or_jungle = "jungle"
          # skip rest of loop and start from top
          continue
    case "jungle":
      print("You are in the jungle!")
      print("The jungle is thick and noisy. You hear water nearby and see  smoke rising through the trees.")
      input("Do you follow the RIVER or the SMOKE?")
