无法将代码格式化为所需的输出

Question

我试图让代码以下面的格式打印，但似乎没有任何效果。有人可以指出代码或逻辑中的错误吗？

所需格式： We have got only 3 oranges and only 1 apple

代码：

excess = {"apple": 5, "orange": 6}
s = ""
for k, v in excess.items():
    n = 1
    if n == 0:
        s = "We have got only {} {} ".format(v, k)
    elif n > 1:
        s += "and {} {}".format(v, k)  
    n += 1
print(bill, s)

输出

We have only 6 orange

Answer 1

您需要在循环外定义n，并将n>1条件替换为n>0（或else）

excess={"apple":5,"orange":6}
s=""
n=0

for k,v in excess.items():
    if n==0:
        s="We have got only {} {}".format(v,k)
    else:
        s+=" and {} {}".format(v,k)  
    n+=1
    
print(s)
# We have got only 5 apple and 6 orange
