现在,我的代码打印出“0角钱”或“0便士”,如果没有硬币或硬币,我需要知道如何制作它,以便如果有一个特定的硬币0,那么什么都不打印那枚硬币。
#Asks user how much change they are trying to give, returns the coins to make that change
coin = int(input("How much change are you tring to give (in cents)? "))
while coin >= 25:
quarters = coin // 25
coin = coin % 25
if coin >= 10:
dimes = coin // 10
coin = coin % 10
if coin >= 5:
nickels = coin // 5
coin = coin % 5
pennies = coin // 1
coin %= 1
print ("You have ",quarters,"quarters", dimes, "dimes,",nickels,"nickels and ",pennies,"pennies.")
例如,如果更改为1个季度和2个镍币,则会打印:(您有1个季度,0个角钱,2个镍币和0个便士)
我需要它来打印(你有1个季度和2个镍币)

这里的字符串连接是你的朋友!不要有一个非常大的印刷声明,尝试这样的事情:
print_str = ''
if quarters > 0:
print_str += 'You have ' + str(quarters) + ' quarters.'
然后,最后打印你的print_str。
作为备注,您可能希望在字符串中包含换行符。 - 我建议在这里阅读字符串:http://www.tutorialspoint.com/python/python_strings.htm

让硬币检查你当前的代码,并在我们去的时候建立输出字符串。请注意,我们永远不会给出多个镍币。
