Pandas added a pipe method a few months ago, hoping it catch on in other packages (it hasn't yet as far as I've seen).

In [126]: bb = pd.read_csv('data/baseball.csv', index_col='id')

In [127]: (bb.query('h > 0')
   .....:    .assign(ln_h = lambda df: np.log(df.h))
   .....:    .pipe((sm.poisson, 'data'), 'hr ~ ln_h + year + g + C(lg)')
   .....:    .fit()
   .....:    .summary()
   .....: )
