date and time range checking

[Maksim Kasimov]

there are few of a time periods, for example:
2005-06-08 12:30 -> 2005-06-10 15:30,
2005-06-12 12:30 -> 2005-06-14 15:30

and there is some date and time value:
2005-06-11 12:30

what is the "pythonic" way to check is the date/time value in the given periods range?

something like xrange:.... print "OK"


thanks

Something like this, though I won't make strong claims of
"pythonicness". If you want to use the "in" keyword you'll want a
custom class and overriding of __contains__.

import time
from datetime import datetime

def make_datetime(s, fmt='%Y-%m-%d %H:%M'):
'''convert string to datetime'''
ts = time.mktime(time.strptime(s, fmt))
return datetime.fromtimestamp(ts)


def inRange(s, ranges):
dt = make_datetime(s)
for begin,end in ranges:
if begin <= dt <= end:
return True
else:
return False


ranges = [(make_datetime(b), make_datetime(e)) for (b,e) in [
('2005-06-08 12:30', '2005-06-10 15:30'),
('2005-06-12 12:30', '2005-06-14 15:30'),
]]

print inRange('2005-06-11 12:30', ranges)

.... print "In range"
....
In range.... print "In range"
....
In range.... print "In range"
....
If you want to use the "in" syntax
.... def __init__(self, low, high):
.... self.low = low
.... self.high = high
.... def __contains__(self, obj):
.... return self.low < obj < self.high
....
