Querying ArcGIS Online


The following code works, output as csv, then read that csv back in as a Dataframe:


x = gis.admin.history(start_date=start_date, to_date=end_date, num=100, data_format='csv')

df = pd.read_csv(x)

Leaving everything the same, but trying to output directly as a Dataframe:

df = gis.admin.history(start_date=start_date, to_date=end_date, num=100, data_format='df')


Produces a TypeError :

TypeError: list indices must be integers or slices, not str

The data variable is a list, so I don’t think we can do this: data['items']


I THINK it’s meant to be: data.extend(res['items']) on line 340 where res is the response from the post  (line 339)

res =, params)


Similarly, on line 345 I changed:

data.extend(data['items'])  -->  data.extend(res['items'])

Everything seems to be working, but wasn’t sure if my “fix” might break something else?  So I was hoping to get some feedback or an “all clear” message that this fix "works" and won't break other things.  Thanks!
