title: Split into columns
body: <p>I want to make 1500 rows x 3 columns data from below output. First [0,1,2] columns there was some information and I deleted them by using .drop . At this point, I have difficulty about dividing them to the columns. Could you help me? Thanks!</p>
  <pre><code>excel_book_1 ='air-accumulation-c5-v2.csv'
  df_1 = pd.read_csv(excel_book_1)
  df_1.drop([0,1,2], inplace=True)
  df_1.columns = range(df_1.shape[1])
  df_1
