复数，如果语句为python [英] Plurals, if statement python

问题描述

这么多问题..目前，我的代码正在计算成本，成人和儿童的数量.如果用户仅输入1个孩子，我希望它打印孩子，而不是孩子.

So many questions.. At the moment my code is calculating the cost, number of adults and children. If the user only inputs 1 child I want it to print child, not children.

serviceType = input("Would you like (M)edium or (R)are steak?")
if serviceType == "r":
    rare = float((noChild * rare) * DISCOUNT) + (noAdult * BASIC)
    print("That is " + formatCurrency(rare) + " for rare choice for " + str(noAdult) + " adults and " + str(noChild) + " children. Enjoy!")

输出显示这是$-2名成人和1名儿童的罕见选择.我需要说这是$-对于1个成人和1个孩子的罕见选择.

The output shows This is $-- for rare choice for 2 adults and 1 children. I need it to say "This is $-- for rare choice for 1 adults and 1 child.

我认为我需要放一个

if noChild == 1

在某处声明，但不确定将其添加到何处?

statement somewhere, but not sure where to add it in?

我也使用相同格式的代码来计算中"，因此我无法将句子更改为child，否则，如果用户输入2，则将是2 child.我希望我已经正确地解释了自己?

I also have the same format of code to calculate "medium" so I can't change the sentence to child, otherwise if the user enters 2 it will be 2 child. I hope I have explained myself properly?

谢谢

推荐答案

您可以这样编写打印语句:

You can write the print statement like this:

print("That is " + formatCurrency(rare) + " for rare choice for " + str(noAdult) +
     (" adult" if noAdult==1 else " adults") + " and " + str(noChild) +
     (" child" if noChild==1 else " children") + ". Enjoy!")
