当我运行代码时，python只是坐在那里不打印任何东西

Question

Exercise: Starting from the back of the string find all the numbers which could possibly lead to a number which is greater than or equal to 100, then stop and find the average of the number before that.

def avgBackwList(values):
    total = 0
    for i in range(1,len(values)+1):
        while values[-i] <= 100:
            total = total + int(values[-i])
    return (total/i)

values = [110,2,4]
print(avgBackwList(values))

Answer 1

线路

        while values[-i] <= 100:

只要values[i]小于或等于100，就会导致函数循环。由于while块中的任何内容都不会更改values[i]，因此如果完全进入循环，它将永远不会终止。你知道吗

您的函数还有其他问题，这意味着它不能正常工作，但首先，您可以尝试将该行更改为

        while total <= 100:

。。。它至少有终止的机会，因为total在while块内被改变。你知道吗
