python之截断整数而不四舍五入

我制作了这个程序来计算零钱和剩余的零钱。它的设置方式是获取找零金额，例如 495，然后将其转换为美元 4.95。现在我想去掉 .95 并保留 4，我该怎么做才能不四舍五入到 5？谢谢!

def main(): 
pennies = int(input("Enter pennies : ")) 
nickels = int(input("Enter nickels : ")) 
dimes = int(input("Enter dimes : ")) 
quarters = int(input("Enter quarters : ")) 
 
computeValue(pennies, nickels, dimes, quarters) 
 
def computeValue(p,n,d,q): 
print("You entered : ") 
print("\tPennies  : " , p) 
print("\tNickels  : " , n) 
print("\tDimes    : " , d) 
print("\tQuarters : " , q) 
 
totalCents = p + n*5 + d*10 + q*25 
totalDollars = totalCents / 100 
totalDollarsTrunc = int(format(totalDollars, '.0f')) 
totalPennies = totalCents - (totalDollarsTrunc * 100) 
 
print("Amount of Change = ", totalDollarsTrunc, "dollars and ", totalPennies ,"cents.") 
 
if totalCents < 100: 
    print("Amount not = to $1") 
elif totalCents == 100: 
    print("You have exactly $1.") 
elif totalCents >100: 
    print("Amount not = to $1") 
else: 
    print("Error") 

请您参考如下方法:

在 Python 中，int() 在从 float 转换时截断:

>>> int(4.95) 
4 

也就是说，你可以重写

totalDollars = totalCents / 100 
totalDollarsTrunc = int(format(totalDollars, '.0f')) 
totalPennies = totalCents - (totalDollarsTrunc * 100) 

使用 divmod 函数:

totalDollars, totalPennies = divmod(totalCents, 100)
