Reading data file with varying number of columns python -


i have data-file first 8 lines of this. (after substituting actual values letters clarity of question)

    a,b,c     d     e,f     g,h     i,j,k     l     m,n     o,p

these represent data transformers in electric network. first 4 lines information transformer 1, next 4 transformer 2 , on.

the variables a-p can either integers, floating-point numbers or strings

i need write script in python that instead of data 1 transformer being spread onto 4 lines, should on 1 line.

more precisely, above 2 lines converted 

  a,b,c,d,e,f,g,h   i,j,k,l,m,n,o,p

and write data-file.
how do this?

use grouper recipe itertools

from itertools import izip_longest def grouper(iterable, n, fillvalue=none):     "collect data fixed-length chunks or blocks"     # grouper('abcdefg', 3, 'x') --> abc def gxx     args = [iter(iterable)] * n     return izip_longest(fillvalue=fillvalue, *args)   open('z.t') f:     d = grouper(f, 4)     x in d:             print ','.join(y.rstrip() y in x)   a,b,c,d,e,f,g,h i,j,k,l,m,n,o,p
