寻找某些关键字“和：

我有一个关于”for“函数和”json“的问题我想从Twitter数据中找到非常具体的关键字写成英文在这里，我将打开JSON文件并从JSON文件我只想在json.load（）前过滤只有英文的数值（）我只想到str（“lang”+'：'+“en”）会返回我的目标数据，但它不会。寻找某些关键字“和：

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")

我不知道我是否可以分享微博的某些部分。但是，下面只是样品。

关键字的价值是什么？显示你的json文件的内容。 – 2015-02-23 03:58:25

你的输入是什么样的？另外，'str（“lang”+'：'+“en”）'没有意义，只需使用''“lang”：“en”''。 – MattDMo 2015-02-23 03:58:59

示例输入和输出？ – Marcin 2015-02-23 03:59:04

看起来像你所需要的条件是

if keyword in line and '"lang":"en"' in line:

你只是简单地阐述这个第二部分古怪，和不正确。
