Project description


  • Python 2.7

$ pip install typedate


you can use as follows:

#!/usr/bin/env python
from typedate import TypeDate, TypeDelta, TypeZone

if __name__ == '__main__':
    import argparse
    parser = argparse.ArgumentParser()

    # datetime parsing
    parser.add_argument("--datetime1", type=TypeDate('%Y%m%d'))
    parser.add_argument("--datetime2", type=TypeDate(timezone='Asia/Tokyo'))
    parser.add_argument("--datetime3", type=TypeDate(timezone='+09:00'))
    parser.add_argument("--datetime4", type=TypeDate(timedelta='1years -2months 3days 4hours 5minute 6seconds'))

    # timezone parsing
    parser.add_argument("--timezone1", type=TypeZone())
    parser.add_argument("--timezone2", type=TypeZone())

    # timedelta parsing
    ## if python-dateutil installed, used automatically dateutil.relativedelta.relativedelta else datetime.timedelta.
    parser.add_argument("--defaultdelta", type=TypeDelta())

    ## it can be specified by cls argument.
    from datetime import timedelta
    from dateutil.relativedelta import relativedelta
    parser.add_argument("--timedelta", type=TypeDelta(cls=timedelta))
    parser.add_argument("--relativedelta", type=TypeDelta(cls=relativedelta))

    args = parser.parse_args()
    print('datetime1:\t', args.datetime1, type(args.datetime1))
    print('datetime2:\t', args.datetime2, type(args.datetime2))
    print('datetime3:\t', args.datetime3, type(args.datetime3))
    print('datetime4:\t', args.datetime4, type(args.datetime4))

    print('timezone1:\t', args.timezone1, type(args.timezone1))
    print('timezone2:\t', args.timezone2, type(args.timezone2))

    print('defaultdelta:\t', args.defaultdelta, type(args.defaultdelta))
    print('timedelta:\t', args.timedelta, type(args.timedelta))
    print('relativedelta:\t', args.relativedelta, type(args.relativedelta))
