Question

对于我的生活，我似乎无法将这些数字加起来！它们都是单独打印的。例如，它显示＆＃34;对于...＆＃34;这将是$ 95.00 $ 90 $ 8.50。我认为这很简单，因为支架编号是正确的......但我似乎无法做到这一点！

print("That is " + str((formatC(pack[packageSelect-1]["adult"]*noAdult) + formatC(pack[packageSelect-1]["child"]*noChild) + (formatC(AREAS.get(delivery))))) + "for " + pack[packageSelect]["name"] +  " package for " + str(noAdult) + " " + adult + " and ", str(noChild) + " " + child + ",  delivered to " + str(deliveryArea.title()) + ".")

我想要＆＃34;成人＆＃34; +＆＃34;孩子＆＃34; +＆＃34;交付＆＃34;总算..不是单独的价格！

Answer 1

您正在添加这些数字的字符串表示形式。字符串的+运算符执行连接。如果您想要添加金额，则必须在float时添加这些金额，然后将结果转换为字符串。

Answer 2

您正在添加格式化字符串;添加字符串将它们一个接一个地放置。

首先添加数字：

total = (
    pack[packageSelect-1]["adult"] * noAdult + 
    pack[packageSelect-1]["child"] * noChild + 
    AREAS.get(delivery))
print("That is " + str(formatC(total)) + "for " + pack[packageSelect]["name"] +  " package for " + str(noAdult) + " " + adult + " and ", str(noChild) + " " + child + ",  delivered to " + str(deliveryArea.title()) + ".")

您可能想要研究如何使用str.format()格式化字符串;它会使您的打印代码更简单，更易读：

print("That is {total} for {pack['name']} package for {noAdult} {adult} and {noChild} {child}, delivered to {area}.".format(
    total=formatC(total), pack=pack[packageSelect], noAdult=noAdult, adult=adult,
    noChild=noChild, child=child, area=deliveryArea.title()))
