python - How can I cut a variable in a for loop each time differently? -

i have document called 'asin.txt':

in,huawei1,de.fr.it.uk out,huawei2,de.fr.it out,huawei3,fr in,huawei4,fr.it in,huawei5,it 

i'm opening file , make ordereddict:

from collections import ordereddict reader = csv.reader(open('asin.txt','r'),delimiter=',') reader1 = csv.reader(open('asin.txt','r'),delimiter=',') d = ordereddict((row[0], row[1].strip()) row in reader) d1 = ordereddict((row[1], row[2].strip()) row in reader1) 

than create 'for' loop:

from itertools import izip (a, b), (c, e) in izip(d.items(), d1.items()):     """in first time: a='in'; b='huawei1'; c='huawei1'; e='de.fr.it.uk'"""     c1, c2, c3, c4 = c.split('.') # i'm cutting variable 'c'     try:        ........... 

but python give me error:

 c1, c2, c3, c4 = c.split('.')  valueerror: need more 3 values unpack 

i know why have error, because in first line of 'asin.txt':

in,huawei1,de.fr.it.uk 

after second coma have 4 countries , , in second line of 'asin.txt'

out,huawei2,de.fr.it 

after second coma have 3 countries. , have statement c1, c2, c3, c4 = c.split('.') .

how can make program cuts c each time on pieces countries in asin.txt?

so exemple in first lap cuts on 4 pieces on second on 3 pieces on third on 1 piece....

you can store results of split list:

clist = c.split('.') 

this way, c "cut" same number of pieces countries in asin.txt.
