cookies_utilities.get_dates

cookies_utilities.get_dates(start='2016-07-01 02:00:00', end='2016-07-02 01:00:00', format='%Y-%m-%d %H:%M:%S', delta={'days': 0, 'hours': 1, 'minutes': 0, 'weeks': 0}, geniter=False, cast_str=True, format_out=None)

Returns a list of times from the ‘start’ time to the ‘end’ time, incremented by ‘delta’.

If you’re using the result as an iterator, it is recommended to set geniter=True.

Parameters:

start (string) – Start time string.
end (string) – End time string (inclusive).
format (string) – Conversion format for datetime.strptime.
delta (dict) – Timedelta as args for datetime.timedelta.
geniter (bool) – Whether to return as a generator iterator (default False).
cast_str (bool) – Whether to convert output to string (default True).
format_out (string) – Conversion format for output (default same to format).

Return type:

list (or generator iterator) of string (or datetime.datetime)

Example

An example of incrementing by one day.

import cookies_utilities as cu
dates = cu.get_dates(
    start='2016/07/01', end='2016/07/03', format='%Y/%m/%d',
    delta={'days': 1}, format_out='%Y-%m-%d')
print(dates)

['2016-07-01', '2016-07-02', '2016-07-03']

An example of incrementing by 20 minutes.

import cookies_utilities as cu
dates = cu.get_dates(
    start='2016-07-01 02:00:00', end='2016-07-01 03:00:00',
    format='%Y-%m-%d %H:%M:%S',
    delta={'minutes': 20})
print(dates)

['2016-07-01 02:00:00', '2016-07-01 02:20:00', '2016-07-01 02:40:00', '2016-07-01 03:00:00']

An example of retrieving as a generator iterator.

import cookies_utilities as cu
dates = cu.get_dates(
    start='2016/07/01', end='2016/07/03', format='%Y/%m/%d',
    delta={'days': 1}, geniter=True)
print(type(dates))
for date in dates:
    print(date)
