title: Filling Python panda dataframes
body: <p>I can write a regular dataframe which has values for rows and columns, however, cant' find a way to write the rows with one entry for e.g. method1, method2..etc, deterministic..). And, also I haven't found a way to split a column ( for e.g. no of bits | 4 ).</p>
  
  <p>This is a single excel file where data will be appended after some interval. Any help will be appreciated :)</p>
  
  <p>Thanks!</p>
