Given an interval from two dates, which will be a Python TimeStamp.
create_interval('2022-01-12', '2022-01-17', 'Holidays')
Create the following dataframe:
| date | interval_name |
|---|---|
| 2022-01-12 00:00:00 | Holidays |
| 2022-01-13 00:00:00 | Holidays |
| 2022-01-14 00:00:00 | Holidays |
| 2022-01-15 00:00:00 | Holidays |
| 2022-01-16 00:00:00 | Holidays |
| 2022-01-17 00:00:00 | Holidays |
If it can be in a few lines of code I would appreciate it. Thank you very much for your help.
If you're open to using Pandas, this should accomplish what you've requested
import pandas as pd
def create_interval(start, end, field_val):
#setting up index date range
idx = pd.date_range(start, end)
#create the dataframe using the index above, and creating the empty column for interval_name
df = pd.DataFrame(index = idx, columns = ['interval_name'])
#set the index name
df.index.names = ['date']
#filling out all rows in the 'interval_name' column with the field_val parameter
df.interval_name = field_val
return df
create_interval('2022-01-12', '2022-01-17', 'holiday')
I hope I coded exactly what you need.
import pandas as pd
def create_interval(ts1, ts2, interval_name):
ts_list_dt = pd.date_range(start=ts1, end=ts2).to_pydatetime().tolist()
ts_list = list(map(lambda x: ''.join(str(x)), ts_list_dt))
d = {'date': ts_list, 'interval_name': [interval_name]*len(ts_list)}
df = pd.DataFrame(data=d)
return df
df = create_interval('2022-01-12', '2022-01-17', 'Holidays')
print(df)
output:
date interval_name
0 2022-01-12 00:00:00 Holidays
1 2022-01-13 00:00:00 Holidays
2 2022-01-14 00:00:00 Holidays
3 2022-01-15 00:00:00 Holidays
4 2022-01-16 00:00:00 Holidays
5 2022-01-17 00:00:00 Holidays
If you want DataFrame without Index column, use df = df.set_index('date') after creating DataFrame df = pd.DataFrame(data=d). And then you will get:
date interval_name
2022-01-12 00:00:00 Holidays
2022-01-13 00:00:00 Holidays
2022-01-14 00:00:00 Holidays
2022-01-15 00:00:00 Holidays
2022-01-16 00:00:00 Holidays
2022-01-17 00:00:00 Holidays
