我有一个关于＆＃34;对于＆＃34;的问题功能和＆＃34; json＆＃34;。 我想从Twitter数据中找到非常具体的英文关键词。 在这里，我将打开JSON文件并从JSON文件中读取行。 我只想在json.load（）之前过滤掉只有英文的值 我认为只有 str（＆＃34; lang＆＃34; +＆＃39;：＆＃39; +＆＃34; en＆＃34;）会返回我的目标数据，但它没有＆＃ 39;吨
with open(filename, "r+") as fi, open(out_file_name, "a") as fo:
for line in fi:
if keyword in line and str("lang"+':'+"en") in line:
fo.write(line + "\n")
我不确定是否可以分享推文的某些部分。但以下只是样本。

答案 0 :(得分：2)
看起来你需要的条件是
if keyword in line and '"lang":"en"' in line:
你只是简单地拼写了第二部分，而且不正确。
