print ("\nSeems we found more than one same mobile type, help us by selecting appropiate model \n")
user_choice = input("\nEnter your choice (number) which matches exactly:")
url_from_search = "http://www.xyzabc.com{}".format(
urldict.get(user_choice).split('&')[0])
有人可以帮我解决这个问题吗?我正在尝试在 beautifulsoup 的帮助下进行 html 解析。上面给出的代码抛出属性错误。可能是什么问题?如果可能的话请帮助我。
最佳答案
显然,user_choice
键不在 urldict
字典内,并且 urldict.get(user_choice)
返回 None
。假设您使用的是 Python 3 并且您的 urldict 键是整数,则需要在查找之前将输入数字转换为整数:
user_choice = int(input("\nEnter your choice (number) which matches exactly:"))
url_from_search = "http://www.acxcs.com{}".format(
urldict.get(user_choice).split('&')[0])
此外,您可能应该更好地处理“丢失 key ”的情况。例如:
user_choice = int(input("\nEnter your choice (number) which matches exactly:"))
if user_choice not in urldict:
print("Error, the number is not valid")
else:
url_from_search = "http://www.acxcs.com{}".format(urldict[user_choice].split('&')[0])
