[Tutor] Tab delim file

[Srinivas Iyyer]

Hello:

I have a nasty file where I have 165 column and 140K
lines. 

For every 12 columns, a new dataset is written. 

0-12 - File A's data is there
13-24 - File B's data is there. 

My task is to write data in each 12 columns to a file.


I have a rough idea, but when I try I am unable to
proceed further. 

f1 = open('my_file.txt','r')
aml = f1.read().split('\n')

fLine = aml[0]

k = len(fLine)/12  # k = 162/12

#So I want to jump k blocks and get the text. 


for line in aml:
   cols = line.split('\t')
   while i > 13:
   ......
I am lost from here... 



Every 4 line(row) contains the file name on which I
have to write the file. 

can any one plese help, i am really stuck in a
problem. 

thanks
srini
