我正在使用Imdbpy库从IMDB获取电影列表的详细信息。但是我无法处理生成的异常。
谁能让我知道我要去哪里错了？
这是代码：
from imdb import IMDb
ia = IMDb()
from_id = 650
to_id = from_id +5
for i in range(from_id,to_id):
try:
movie_id = ia.get_movie(i)
title = movie_id['title']
release_year = movie_id['year']
kind = movie_id['kind']
movieid = movie_id.movieID
print ("here", title,kind,movieid)
except:
pass
出现异常时，我什么也不想做。我希望它跳过它。
我什至尝试了
except Exception as e。但这没有帮助。它仍然会引发错误。这是错误：

我收到ID = 652的错误消息。
有人请帮我解决这个问题。
最佳答案
实际上，您正在处理异常，您只是决定不做任何处理。
您的代码由于异常处理而继续执行，并且在错误中还有正确的行：
here The Boston Tea Party movie 0000650
here The Boy Detective, or The Abductors Foiled movie 0000651
here A Calamitous Elopement movie 0000653
here The Call of the Wild movie 0000654
如果删除try-catch，则代码将在第一个错误时停止执行。
我认为打印错误是因为imdbpy内部的某些命令正在打印标准错误。如果要避免这些错误，可以通过以下方式启动脚本，例如将标准错误重定向到
/dev/null或文件：python3 my_imdb.py 2> /dev/null
