我抓住这样的例外,

def get_url_fp(image_url, request_kwargs=None):
    response = requests.get(some_url, **request_kwargs)
    response.raise_for_status()
    return response.raw


try:
   a = "http://example.com"
   fp = get_url_fp(a)

except HTTPError as e:
    # Need to check its an 404, 503, 500, 403 etc.

我是一个蟒蛇初学者.我试图运行此代码:

def main():
    print ( " This program computes the average of two exam scores . ")
    score1,score2 = input ("Enter two scores separated by a comma:")
    average = (score1 + score2)/2.0
    print ("The average of the score is : " , average )

当我召唤时,main()我得到了这个ValueError:

ValueError: too many values to unpack (expected 2)

这段代码有什么问题？
