While 循环需要 1 个参数，但需要更多[重复]

Question

我正在尝试为我的飙车模拟游戏创建一个升级商店，但它一直显示“TypeError：输入预计最多 1 个参数，得到 19” 我对Python有点陌生，所以有人可以像新手一样帮我解释一下吗？

upgradeQ=input("\nWould you like to purchase an upgrade? (y/n) ")
while upgradeQ=="y":
upgradeList=int(input("\n1. Engine ($1000)",userEngine,"/ 5",
                  "\n2. Spoiler ($250)",userSpoiler,"/ 6",
                  "\n3. Body ($750)",userBody,"/ 6",
                  "\n4. Wheels ($500)",userWheels,"/ 10",
                  "\n5. Exhaust ($250)",userExhaust,"/ 5",
                  "\n6. Transmission ($500)",userTrans,"/ 4",
                  "Which upgrade would you like to purchase? (1-6) "))

# Engine Upgrades
if upgradeList==1 and (bank-enginePrice)<0:
    print("\nYou do not have sufficient funds!")
    upgradeQ=input("\nWould you like to purchase an upgrade? (y/n) ")
elif upgradeList==1 and (userEngine>=6):
    print("\nYou have the maximum upgrades for engine.")
    upgradeQ=input("\nWould you like to purchase an upgrade? (y/n) ")
elif upgradeList==1 and (bank-enginePrice)>0:
    bank-=enginePrice
    userEngine+=1
    print("\nSuccess! You have purchased the Engine upgrade.")
    upgradeQ=input("\nWould you like to purchase an upgrade? (y/n) ")

“您想购买哪个升级？(1-6)”))的upgradeList最后一行显示了TypeError

你的问题很可能就在这里

upgradeList=int(input("\n1. Engine ($1000)",userEngine,"/ 5",
                  "\n2. Spoiler ($250)",userSpoiler,"/ 6",
                  "\n3. Body ($750)",userBody,"/ 6",
                  "\n4. Wheels ($500)",userWheels,"/ 10",
                  "\n5. Exhaust ($250)",userExhaust,"/ 5",
                  "\n6. Transmission ($500)",userTrans,"/ 4",
                  "Which upgrade would you like to purchase? (1-6) "))

, 运算符不连接字符串。相反，每个逗号标记另一个参数。

functioncall(arg1, arg2, arg3) etc

输入函数只接受一个参数，从类型错误中可以看出。

将那些 , 更改为 + 就可以了。您可能需要将一些内容转换为字符串，但这是另一个问题（并且很容易通过谷歌搜索）

我猜您查看了 print 函数并假设这就是所有函数的工作原理。 Print 是一个例外，因为它是可变参数，因此可以接受任意数量的参数
