The directory layout looks like this

base -- +
        parcer -- +
               parcer.py
        log    -- +
               log.py

I want to import log.py from parcer.py. How would I do that?

import sys
sys.path.append("..\\log") #(windows style) path to the module
import log

Maybe better to use os.path.join, works also in not-Windows (or should I say Windows' complement :-) )

import sys,os
>>> sys.path.append(os.path.join('..','log'))
>>> sys.path[-1]
'..\\log'
>>>
