Extract certain dataframes of lists of dataframes
Question:
I have a list of dataframes. Each is build up as followed:
No i want to extract the dataframes beginning at a certain time.
Collection=[]
for i in range(len(subdfs)):
if any(subdfs[i]['Zeitpunkt'][subdfs[i]['Zeitpunkt'].dt.hour.eq(12)]):
Collection.append(subdfs[i]['Zeitpunkt'])
With this code i am able to extract every dataframe where the hour 12 appears. But i only want the dataframes where the hour 12 is in the first row.
Answers:
Try:
Collection = [subdf for subdf in subdfs if subdf.iloc[0, subdf.columns.get_loc('Zeitpunkt')].hour == 12]
It worked with:
Collection = [subdfs for subdfs in subdfs if subdfs.iloc[0, 1].hour == 12]
