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: a = xrange(1,5) b = 3 if b in a:
.... print "OK"
thanks

Something like this, though I won't make strong claims of
"pythonicne ss". 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(tim e.strptime(s, fmt))
return datetime.fromti mestamp(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)

If you want to use the "in" syntax
class InRange:

.... self.low = low

.... return self.low < obj < self.high

Hi,
Anyone know if the Standard has anything to say about the time complexity
of size() for std::set?
I need to access a set's size (/not/ to know if it is empty!) heavily
during an algorithm and was thus wondering whether I'd be better off
tracking the size "manually" or whether that'd be pointless.
