Easy time class supporting chain called, deprecated name: py-itime
Project description
timez is a time package supporting chain call.
install and use:
pip install timez
Example
from timez import timez # get datetime str of previous day with specified hours >>> timez(f'{timez.now().delta(days=-1).date_str()} 10:00:00').datetime_str() '2021-04-04 10:00:00' # get unix timestamp of previous day >>> timez.now().delta(days=-1).uts(is_ms=True) 1627211818635 # get corresponding unix timestamp with specified datetime str >>> timez('2021-04-04 18:23:12').uts() 1617531792 # get datetime str of UTC time which is converted and down sampled by local time >>> timez.now().delta(hours=8).ds(minutes=5).datetime_str() '2021-04-04 08:05:00'
Initialize
There are 5 ways to initialize an timez object.
# 1. init with time str, format '%Y{}%m{}%d', '%Y{}%m{}%d %H{}%M{}%S' date_sep could be '','-','/', time_sep could be '',':'. >>> timez('20210404') >>> timez('2021-04-04 18:23:12') >>> timez('2021/04/04 18:23:12') # 2. init with unix timestamp, support second and milliseconds, default as second >>> timez(1617531792) >>> timez(1617531792000, is_ms=True) # if is milliseconds, is_ms=True >>> timez(1617531792.123) # float is also supported # 3. init with custom datetime str, use timez.strp(time: str, fmt: str) >>> timez.strp('2021-04-04 18:23', fmt='%Y-%m-%d %H:%M') # 4. init datetime.datetime object >>> dt = datetime.datetime.now() >>> timez(dt) # 5. init with timetuple >>> timez((2021, 4, 4, 18, 23, 12)) >>> timez(['2021', '04', '04', '18', '23', '12'])
class timez
- timez.now() -> timez
get current local time.
- timez.today() -> timez
get current date, hour minute second is 00:00:00.
- timez.strp(time: str, fmt: str) -> timez
init timez from custom time str format.
- timez.uts(is_ms=False) -> int
get unix timestamp, if is_ms=True, get milliseconds.
- timez.date_str(date_sep=’-’) -> str
get date str, sep include ‘’, ‘-’, ‘/’.
- time_str(time_sep=’:’) -> str
get time str, ‘time_sep’ is sep include ‘’, ‘:’.
- datetime_str(date_sep=’-’, time_sep=’:’) -> str
get datetime str, date_sep and time_sep same to above.
- join(datetime_str: str, fmt: str) -> timez
join timez self with given time str. Notice: There is no date or time range checking, be careful
- ::
>>> timez('2021-04-04 18:23:12').join('23:59:59').__str__() '2021-04-04 23:59:59' >>> timez('2021-04-04 23:59:59').join('10 235959', fmt='%d %H%M%S').__str__() '2021-04-10 23:59:59' >>> timez('2021-04-04 18:23:12').join('10', fmt='%d').__str__() '2021-04-10 18:23:12'
- strf(fmt) -> str
get custom time str with given fmt.
- pop() -> datetime.datetime
get datetime.datetime object from timez instance
- delta(days=0, seconds=0, minutes=0, hours=0) -> timez
get offset time.
- ds(hours=None, minutes=None, seconds=None) -> timez
down sample time, example as follows.
- ::
>>> timez('2021-04-04 18:23:12').ds(hours=5).__str__() '2021-04-04 15:23:12' >>> timez('2021-04-04 18:23:12').ds(minutes=5).__str__() '2021-04-04 18:20:12' >>> timez('2021-04-04 18:23:12').ds(seconds=5).__str__() '2021-04-04 18:23:10' >>> timez('2021-04-04 18:23:12').ds(minutes=5, seconds=0).__str__() '2021-04-04 18:20:00' >>> timez('2021-04-04 18:23:12').ds(hours=0, minutes=0, seconds=0).__str__() '2021-04-04 00:00:00' >>> timez('2021-04-04 18:23:12').ds(hours=17, minutes=5, seconds=5).__str__() '2021-04-04 17:20:10'
