bda.intellidatetime provides a converter for date and time input to python datetime.datetime objects.
The input format is definded by a locale2pattern mapping and is provided by a seperate interface.
Currently provided locales are:
- and the special locale iso, which is used as default.
Use the convert function:
>>> from bda.intellidatetime import convert >>> convert('1.1.08', locale='de') datetime.datetime(2008, 1, 1, 0, 0)
The signature of bda.intellidatetime.convert looks like so:
def convert(date, time=None, tzinfo=None, locale='iso'): """Convert the input to a datetime object. The convert function accepts unicode or non-unicode strings and tries to parse out Date and Time information as follows: * First try to get the localized datetime pattern information * If no one is found, a default pattern is used. * Parse the input by the definitions of the localized datetime pattern * Create a datetime object and return it The 'intelligence' is defined by following behaviour: Date: * If only one value is found f.e. '1', this value is handled as the day value, for month and for year the current ones are used. * Respective, if two values are given, they are handled as day and month, year is auto completed with the current year. * 3 values are a complete date information, if year is a 2-character string, it is handled as year in the current century * as limiters are all non-numeric values accepted * date input can be done without limiters, therefor all characters must be numbers, and the string length must be either 2, 4, 6 or 8 characters. 2 characters define the day, 4 characters the day and the month, 6 characters day, month and the year of the current century and 8 characters define a complete date. Time: * If time is None, time is set to 00:00 * if time is a 2-character string, it is handled as the hour, minutes are defined as 00 * time input can be done without a limiter, therefor time must be an all numeric 4-character string, the first 2 chars are handled as hour, the second 2 chars as minute. * as limiter are all non-numeric values accepted * seconds are never computed and are therefor ALWAYS handled as '00' Limiters can be any 1 or more character non numeric values. An input can look like `` %_2008 1 abcde 5 ---`` and is still valid and with default locale converted to ``datetime.datetime(2008, 1, 5, 0, 0)``. If parsing of the input values is not possible or converting the parsed values to numeric values is not possible or the valid date and time range falls out of scope, a ``DateTimeConversionError`` is raised. @param date - a date as string @param time - a time as string @param tzinfo - a tzinfo object to be considered, defaults to None. If given the date and time taken as in the given timezone. If the timezone is DST-aware time will be normalized for DST/non-DST. @param locale - a locale name, which is used to determine the date and time patterns. There exists a special locale named 'iso', which is default and expects the input in ISO format. @return datetime - datetime.datetime object @raise DateTimeConversionError - if conversion fails """
