I need to upsample sales_df for each day.

sales_df.resample('D', how='last').ffill() gives

FutureWarning: how in .resample() is deprecated the new syntax is .resample(...).last()

Can someone give the correct syntax or the url of documentation?

Also need the syntax for pad and interpolate

Use: `sales_df.resample('D').last().ffill()` – jezrael Dec 21 '19 at 10:23
Any url giving examples of the latest syntax on resampling of dataframe? – kakoli Dec 21 '19 at 10:33
[docs](https://pandas.pydata.org/pandas-docs/version/0.25/user_guide/timeseries.html#resampling) – jezrael Dec 21 '19 at 10:35
sales_df.resample('D', how='last').ffill() results are correct – kakoli Dec 21 '19 at 13:14
yop, if use some old pandas version under `0.18` then yes, it is correct way, else return `FutureWarning` – jezrael Dec 21 '19 at 13:16
sales_df.resample('D', how='last').ffill() does it inplace sales_df.resample('D').last().ffill() does it on a copy – kakoli Dec 21 '19 at 13:25
