I have this dictionary
example = {
'view_id_ga_standard_111': {'view_id': '111',
'request_type': 'ga_standard',
'start_date': '2019-07-01',
'end_date': '2019-09-01',
'status': 'New'},
'view_id_ga_standard_333': {'view_id': '333',
'request_type': 'ga_standard',
'start_date': '2019-07-01',
'end_date': '2019-09-01',
'status': 'New'},
'view_id_ga_corporate_222': {'view_id': '222',
'request_type': 'ga_corporate',
'start_date': '2018-07-01',
'end_date': '2018-09-01',
'status': 'New'}
}
And need to make a pandas df out of it, so it looks like this
id request_type start_date end_date request_id status
2 111 ga_standard 2019-07-01 2019-09-01 1 New
3 333 ga_standard 2019-07-01 2019-09-01 2 New
5 222 ga_corporate 2018-07-01 2018-09-01 3 New
I have ended up with this function
def ga_make_request_types(params):
vids = []
rtypes = []
sdates = []
edates = []
js = []
statuses = []
j = 0
for k,v in data_for_config.items():
j = j + 1
view_id = v['view_id']
vids.append(view_id)
request_type = v['request_type']
rtypes.append(request_type)
start_date = v['start_date']
sdates.append(start_date)
end_date = v['end_date']
edates.append(end_date)
status = v['status']
statuses.append(status)
js.append(j)
df = pd.DataFrame(zip(vids, rtypes, sdates, edates, js, statuses), columns=['id', 'request_type', 'start_date', 'end_date', 'request_id', 'status'])
return df
But it is quite ugly, is it possible to shorten the code with list comprehensions?
I have tried like this
for k,v in data_for_config.items():
vids = [v['view_id'] for v in k]
and like this
for k,v in data_for_config.items():
vids = [v['view_id'] for v in data_for_config[k]]
But it throws an error
TypeError: string indices must be integers
How about:
df = pd.DataFrame(example).T
Output:
end_date request_type start_date status view_id
view_id_ga_corporate_222 2018-09-01 ga_corporate 2018-07-01 New 222
view_id_ga_standard_111 2019-09-01 ga_standard 2019-07-01 New 111
view_id_ga_standard_333 2019-09-01 ga_standard 2019-07-01 New 333
Edit:
I'm not sure how request_id
is determined, but you could do something like:
df['request_id'] = range(1, df.shape[0] + 1)
Load the dict and Transpose DataFrame
pd.DataFrame(example).T.reset_index(drop=True).rename(columns={'view_id':'id'})
id request_type start_date end_date status
0 111 ga_standard 2019-07-01 2019-09-01 New
1 333 ga_standard 2019-07-01 2019-09-01 New
2 222 ga_corporate 2018-07-01 2018-09-01 New
