Question

我想知道如何在python中我能够编写代码，而不是在用户输入某个输入之前执行代码，例如，

a = 1
raw_input("type a if you want to run '1'")

但不是没有＆＃39; 1＆＃39;在这个例子中，它将是代码。并且直到用户输入＆＃39; <＃39;

才会运行

好的：这是我正在进行的游戏的一部分：

balance = 2500
FinalPrice = 0
buy = input("Marijuana plants cost 200$ ea, opium seeds cost 300$")     
while (buy != "o") and (buy != "m"):
    buy = input("That's not on the market! type 'm' if you want to buy Marijuana and 'o' if you want opium!")

if buy =="o":
    o = input("How many opium seeds? Press c to cancel")
    if o =="c":
       input("You cancelled the trade. Type in a command to do something else")
elif buy =="m":
    m = input("How many Marijuana plants? Press c to cancel")
    if m=="0":
        m = input("invalid number, input again")
    elif m =="c":
        input("You cancelled the trade. Type in a command to do something else")
    mprice = (m*200)
    print(mprice)
    FinalPrice-=FinalPrice
    FinalPrice+=mprice
    mbuy = input("This is the final price, press b to buy or c to cancel")
    if mbuy =="c":
        input("You cancelled the trade. Type in a command to do something else")
    elif mbuy =="b":
        if mprice > balance:
            print("Not enough money! Sell more drugs to earn more money.")
        elif mprice < balance:
            print("you bought", m , "Marijuana plants for", mprice , "$")
input("What do you want to do next?"

我希望在用户输入输入时移动所有这些代码，例如＆＃34; buy＆＃34;它会执行此代码，但只有这样，当我向用户询问下一步要做什么时，我不想在每次输入后复制+粘贴它

您想声明一个函数。

def buy():
    #paste all your code in here

现在，只要您想运行该功能，您只需要调用它即可。您可以以相同的方式定义许多其他函数并调用它们，而无需复制和粘贴任何代码。

command = input("Type buy if you want to buy, and sell if you want to sell.")
if command == 'buy':
    buy()
elif command == 'sell':
    sell()

我强烈建议您阅读评论中已经链接的文档。将平衡和FinalPrice作为参数传递给函数并在最后返回它们是更好的编程习惯，甚至更好地为每个价格定义单独的变量，但阅读文档可能比在这里要求更多。

什么方式让我在脚本中有代码，但在被问到之前没有运行？
