title: Combinging Multiple Json Objects as one DataFrame in Python Pandas
body: <p>I'm not sure what I'm missing here but I have 2 zip files that contain json files and I'm just trying to combine the data I extract from the files and combine as one dataframe but my loop keeps giving me separate records. Here is what I have prior to constructing DF. I tried pd.concat but I think my issue is more to do with the way I'm reading the files in the first place. </p>
  
  <pre><code>data = []
  for FileZips in glob.glob('*.zip'):
      with zipfile.ZipFile(FileZips, 'r') as myzip:
          for logfile in myzip.namelist():
              with myzip.open(logfile) as f:
                  contents = f.readlines()[-2]
                  jfile = json.loads(contents)
                  print len(jfile)
  </code></pre>
  
  <p>returns: </p>
