货币转换器

AmirBreakable电视

我有一个问题，该程序无法显示用户想要转换的所需金额。另外，您如何将数字四舍五入到小数点后三位？

money = int(input("Enter the amount of money IN GDP you wish to convert :"))

USD = 1.25
EUR = 1.17
RUP = 83.87
PES = 25.68

currency = input("Which currency would you like to convert the money into?")

if currency == "USD":
    print(money) * USD
elif currency == "EUR":
    print(money) * EUR
elif currency == "RUP":
    print(money) * RUP
elif currency == "PES":
    print(money) * PES

Python包含允许您指定所需位数的round()功能。因此，您可以使用进行四舍五入至小数点后三位的普通舍入。round(x, 3)

例子

print(round(5.368757575, 3)) # prints 5.369

更新

您可以通过这种方式更新代码。

money = int(input("Enter the amount of money IN GDP you wish to convert: "))

USD = 1.25
EUR = 1.17
RUP = 83.87
PES = 25.68

currency = input("Which currency you like to convert the money into?: ")

if currency == "USD":
    print(round(money * USD, 3))
elif currency == "EUR":
    print(round(money * EUR, 3))
elif currency == "RUP":
    print(round(money * RUP, 3))
elif currency == "PES":
    print(round(money * PES, 3))

它输出：

Enter the amount of money IN GDP you wish to convert: 100
Which currency you like to convert the money into?: USD
125.0

Enter the amount of money IN GDP you wish to convert: 70
Which currency you like to convert the money into?: RUP
5870.9
