notebook example for transfering code from pure pandas to dask #68

Open sephib opened 5 years ago

sephib commented 5 years ago

Hi, I'm writing a notebook example to highlight some key differences between pandas and dask. Are you interested in such a PR? If so i have currently the following topics - (are there any additional topics that I should include?) :

  1. Dask does not update - thus no "inplace=True": (e.g. rename, reset_index, dropna,)
  2. reading/saving dataframes (with *)
  3. some gotcha's with index
  4. dd.Aggregatoin vs groupby.apply

Sure, something like that seems nicely in scope. I look forward to seeing what you come up with!
