我是 python 新手，所以我對“if”句子有 1 個問題。我有 3 個變數，我需要在螢屏上顯示 1 條訊息，就像 Millage 是“”一樣，看：
我有 3 個城市，如果我寫 1 顯示里程，但如果不存在顯示“找不到地址再試一次”，當我使用 else 時，如下所示：
else: print(Fore.GREEN "\n地址未找到，再次檢查地址")
給我看句子“not found check again”，但也顯示millage，我不知道我是否解釋得很好，但如果有人可以幫助生病 B 感激不盡。
destino1 = "Tuscalosa AL"
destino2 = 'Warren OH'
destino3 = "Atlanta GA"
if address in (destino1):
print(Fore.WHITE "\nTotal Miles ", "\033[34m","935 miles")
if address in (destino2):
print(Fore.WHITE "\nTotal Miles ", "\033[34m", "1600 miles")
if address in (destino3):
print(Fore.WHITE "\nTotal Miles ", "\033[34m", "1107 miles")
else:
print(Fore.GREEN "\nAddress not Found, check address again")

我認為你想要的是這種結構：
if address in (destino1):
print(Fore.WHITE "\nTotal Miles ", "\033[34m","935 miles")
elif address in (destino2):
print(Fore.WHITE "\nTotal Miles ", "\033[34m", "1600 miles")
elif address in (destino3):
print(Fore.WHITE "\nTotal Miles ", "\033[34m", "1107 miles")
else:
print(Fore.GREEN "\nAddress not Found, check address again")

使用if - elif - else格式。
如果我正確理解您的問題，您正在嘗試為用戶輸入的城市列印里程，但如果輸入的城市不是來自給定的三個，您想要列印“未找到”陳述句。
你可以做這樣的事情，
if address==destion1:
print(milage for destion1)
elif address==destion2:
print(milage for destion2)
elif address==destion3:
print(milage for destion3)
else:
print("Not found statement")
其他建議 最好使用 dict 或 list 而不是宣告 3 個變數。您可以縮短條件陳述句和整體代碼，如下所示，
destinations = {"dest1" : "milage1", "dest2" : "milage2", "dest3" : "milage3"}
if address in destinations:
print(f"Milage for {address} is {destinations[address]})
else:
print("Destination not found")

用這個：
if address in (destino1):
print(Fore.WHITE "\nTotal Miles ", "\033[34m","935 miles")
elif address in (destino2):
print(Fore.WHITE "\nTotal Miles ", "\033[34m", "1600 miles")
elif address in (destino3):
print(Fore.WHITE "\nTotal Miles ", "\033[34m", "1107 miles")
else:
print(Fore.GREEN "\nAddress not Found, check address again")
