我試圖在 python 中制作一個簡單的基于文本的冒險游戲，并且遇到了一個小錯誤，即在我不希望它調(diào)用時調(diào)用了 else 命令。以下是我的代碼中的一個小示例。## inventory var ## inv=["torch"] ## inventory function ## def ichk(): print(f" You are carrying{inv}") return##First room, links to a3## def a2(): move=input("placeholder text.. You notice an exit to your 'east': ") if move==("e"): print("You exit to the east") a3() if move==("i"): ichk() if move==("q"): print("You find nothing of value") a2() else: print("You can't move in that direction") a2() 當(dāng)函數(shù) ichk() 被觸發(fā)時（通過用戶輸入“i”），庫存被打印，然而在返回到函數(shù) a2() 的開頭之前，else 打印語句也被打印。我是 python 的新手，所以我知道構(gòu)造的參數(shù)可能不是高效/有效的編碼，但我不確定為什么會觸發(fā)它。

當(dāng)你像那樣鏈接它們時你需要使用elif語句，否則輸入'i'，if你擁有的第三條語句將為假并運行相關(guān)else語句：
## inventory var ##
inv=["torch"]
## inventory function ##
def ichk():
print(f" You are carrying{inv}")
return
##First room, links to a3##
def a2():
move=input("placeholder text.. You notice an exit to your 'east': ")
if move==("e"):
print("You exit to the east")
a3()
elif move==("i"):
ichk()
elif move==("q"):
print("You find nothing of value")
a2()
else:
print("You can't move in that direction")
a2()

在Python中，如果有多個條件語句，需要寫成：if,elif,elif,elif,....,else
## inventory var ##
inv=["torch"]
## inventory function ##
def ichk():
print(f" You are carrying{inv}")
return
##First room, links to a3##
def a2():
move=input("placeholder text.. You notice an exit to your 'east': ")
if move==("e"):
print("You exit to the east")
a3()
elif move==("i"):
ichk()
elif move==("q"):
print("You find nothing of value")
a2()
else:
print("You can't move in that direction")
a2()
