如何解决：“ int”对象不可迭代

Question

我正在尝试运行这段代码，并且收到一条错误消息'int' object is not iterable for line 10。不知道我哪里出错了。

def inputVal(prompt,lower,upper):
    print(prompt)
    retVal = int(input())
    while retVal<lower or retVal>upper:
        print('Incorrect Value')
        retVal = int(input())
    return retVal

numComp = inputVal("Please enter number of competitors", 5, 20)

for comp in numComp:
    total=0
    for i in range(5):
        judgescore = inputVal('Please input judges score', 0, 10)
        total = total + judgescore
    print("Total judge score for competitor ", comp+1, "is: ", total)
    print("Average judge score for competitor ", comp+1, "is: ", total/5)

Answer 1

它来自以下行：

for comp in numComp:

因为numComp是int来自用户的。并且ints不能被迭代（对一个数字进行迭代没有任何意义）

也许您的意思是：

for comp in range(numComp):
