I'd recommend using a regex replace for this instead of what you're currently using.

import re

def main():
  fileR=open('test.txt','r')
  for line in fileR:
    line = re.replace(r'
$','',line)
    print line

Or, if you want, you can just replace all of them at once before printing out each line individually because python's regex is global by default.

import re

def main():
  fileR=open('test.txt','r')
  fileR = re.replace(r'
$','',fileR)
  for line in fileR:
    print line
