Remove line breaks from a text file

[Chris9]

I have an ASCII table where each row is a line. I'd like to replace each line break with a space so that i end up with one very long row. Any ideas? Thanks!

import re

in_fd = open(in_fn, "r")

file_lines = in_fd.readlines()

out_fd = open(out_fn, "w")

for lines in file_lines:
    new_line = re.sub("\n", "", lines)
    out_fd.write(new_line)

out_fd.close()
in_fd.close()

I prefer this non re solution.

fn1 = "text4.txt"
fn2 = "text5.txt"

f1 = open(fn1)
f2 = open(fn2, 'w')
outputList = [line.strip() for line in f1]
f1.close()
f2.write(" ".join(outputList))
f2.close()
