I am trying to write to a file multiple times before close. Using the following sequence:

outfile = open(data_file, 'w' )
x=5
while x > 0
x = x - 1
datax is read from a file.

outfile.write('%25s' %datax + "|\n")

This loop will write 5 lines at column position 25. I later come back to the same code and want to write 5 more lines at column 50 starting on line 1 and not line 6.

My questions are:

1. how can I format outfile so i can write multiple lines and then apend multiple lines later before closing the file?

2. how can I make data formatting string '%25s' intiger (in this case 25) a variable?

Thanks in advance.

open(data_file, 'w');

x = 5;
while(x > 0):
    x -= 1;
open(data_file, 'a').write('%25s' %datax + "|\n");

Im a bit confused on what you want '%25s' %datax + "|\n" to do.
