I have a dataframe similar to the one below:
ID Award Type Date 01 PELL FED 2021-06-01 01 SCH LOC 2021-06-01 02 SCH LOC 2021-06-04 03 GRANT STA 2021-06-02 03 PELL FED 2021-06-15 03 SCH LOC 2021-07-01I want to convert this to the following dataframe:
ID Award Type Date 01 PELL, SCH FED, LOC 2021-06-01, 2021-06-01 02 SCH LOC 2021-06-04 03 GRANT, PELL, SCH STA, FED, LOC 2021-06-02, 2021-06-15, 2021-07-01In this case, I am grouping by ID. However, there may be more than one grouping column (for instance, ID and TERM instead of just ID). I have the grouping columns stored in a list variable named 'keys'.
Each grouping could have a different number of items, but the non-grouping columns all have the same number of items for each group (for ID=01 in the dataframes above, the other columns will all have 2 rows).
All the columns are read in as strings from a csv file (using dtype=str on pd.read_csv) to prevent changing any of the values from their original value (I don't want numbers reinterpreted or date formats changed).
I have tried something along the lines of the following, but none of these seem to work.
...ANSWER
Answered 2021-Oct-08 at 03:04Try this -
- Create a dictionary that has all the required columns except
ID
as key andlambda x: list(x)
as function. - Use
groupby
withagg
to apply the independent functions on each column. - If you want to convert the
list
to a concatenated string, then just change the lambda function tolambda x: ', '.join(list(x))
More details on how to work with complex groupby and aggregates can be found on my blog here, if you are interested.

...ANSWER
Answered 2021-Apr-27 at 16:44You can do it with the $event
parameter.
Make sure to compare your values safely.
If your value is not in the right type or has spaces or unwanted chars, this c.state == val
might not work.
You can use the trim
function to compare your value safely:
c.state.trim() == val.trim()
