Dear Friends,
Very often you need to cut a large file in small files which contains equal number of lines. Consider the following scenerio:
I have a text files which contains 1000000 lines. I want to split it in files that contains 15000 lines each. E.g, first file contains 1 to 15000 lines, next file 15001 to 30000 lines and so on.
The following script will not only do so, but it will also create files with meaningful names.

The following script will not only do so, but it will also create files with meaningful names.
lines = open('myfile.txt').readlines()
for i in range(0, 1000000, 15000):
open('{0}_{1}.txt'.format(i+1, i+15000), 'w').writelines(lines[i:i+15000])
----------------------------------------------------------------------
Notes:
1. This will create files with names line 1_15000.txt which contain lines 1 to 15000,
15001_30000.txt which contain lines 15001 to 30000 and so on.
