The best way to filter a log by a dates range in python

Question

What\'s the best way to print log lines that match a datetime range. For example:

I would like to print only lines with dates from: 2012/09/30-00:00:10 to: 2012/09/

Answer 1

Actullay, the log format allows to compare date strings without their conversion to datetime.

with open('mylog.log','r') as f:
    for line in f:
        d = line.split(" ",1)[0] 
        if d >= '2012/09/30-00:00:10' and d <= '2012/09/30-00:00:13':
            print line
