Question

我不知道一点python和下面的脚本输出6小时谷歌研究。我的任务很简单。想要创建一个文本文件，其中包含从OMDB中提取的电影信息。我将所有电影名称转储到文本文件中并运行以下脚本。每次我运行以下脚本时，我只得到15-20个电影信息，但之后我得到解码器错误。当我通过删除已经获得信息的电影名称重新运行时，我再次获得10-15电影信息！我不是Python的专家，但下面的一切看起来都很好，所以不确定为什么我会得到这个。

import json
import requests
import sys
import time

if(len(sys.argv) != 2):
    print("Please provide the movie file name as input arg. Ex " + sys.argv[0] + " movie_names.txt")
    print("Please note that in movie file each movie name should be on a new line")
else:
    with open(sys.argv[1]) as f:
        for line in f:
            json_obj_movie_detail = requests.get ("http://www.omdbapi.com/?t=\"" + line.rstrip('\n') + "\"&apikey=$$$$$$$")
            j = json.loads( json_obj_movie_detail.content )
            if(j.get('Title')):
                print (j['Title']+ ";" , end='', flush=True)
            else:
                print (line.rstrip('\n') + ";" + "Could not find this movie!", end='', flush=True)

            if(j.get('Genre')):
                print (j['Genre']+ ";" , end='', flush=True)
            else:
                print ("null" + ";", end='', flush=True)

            if(j.get('Plot')):
                print (j['Plot']+ ";" , end='', flush=True)
            else:
                print ("null" + ";" , end='', flush=True)

            counter = 0

            if(j.get('Title')):
                for each_rating_source in j['Ratings']:
                    print (j['Ratings'][counter]['Source'] + ";", end='', flush=True)
                    print (j['Ratings'][counter]['Value'] + ";", end='', flush=True)
                    counter = counter + 1
            else:
                print ("null", end='', flush=True)

            print(" ")

    f.close()

非常感谢Python / Json专家提供的帮助。

频繁的json解码器错误 - decoder.py第357行，在raw_decode中
