Dppd is a python dplyr clone.

It allows you to use code like this

   >>> from plotnine.data import mtcars
   >>> from dppd import dppd
   >>> dp, X = dppd()
   >>> dp(mtcars).mutate(kwh = X.hp * 0.74).groupby('cyl').filter_by(X.kwh.rank() < 2).ungroup().pd
      cyl              name   mpg   disp   hp  drat     wt   qsec  vs  am  gear  carb     kwh

Briefly, it uses a data-manipulater instance (dp above) together with a proxied reference to the latest created DataFrame (the X above) to achive for pandas what dpylr's non-standard-evaluation based verbs does for R.

Please see our full documentation at https://dppd.readthedocs.io/en/latest/ for more details and a list of the supported verbs.
