divide group data base on select columns values?

df

   ts_code    type  close

  0 861001.TI   1   648.399
  1 861001.TI   20  588.574
  2 861001.TI   30  621.926
  3 861001.TI   60  760.623
  4 861001.TI   90  682.313
  ...   ... ... ...
  8328  885933.TI   5   1083.141
  8329  885934.TI   1   951.493
  8330  885934.TI   5   1011.346
  8331  885935.TI   1   1086.558
  8332  885935.TI   5   1028.449

Goal

ts_code    l5d_close l20d_close …… l90d_close
861001.TI   NaN       1.10          0.95
……           ……       ……            ……

I want to groupby ts_code to calculate the close of type(1)/the close of type(N:5,20,30……). Take 861001.TI for example, l5d_close is nan because there is no value when the type is 5. l20d_close equals 648.399/588.574=1.10, l90d_close equals 648.399/682.313=0.95. And the result is rounded.

Try

df.groupby('ts_code')\
  .pipe(lambda x: x[x.type==1].close/x[x.type==10].close)

Got: KeyError: 'Column not found: False'

The type values is: 1,5,20,30,60,90,180,200

Notice: There is one value of type columns for each ts_code
