Python code for replacing texts not working

Vote count:

My code is this.

import fileinput
for line in fileinput.FileInput("aaaa.txt",inplace=1):
     map_dict = {'\N':'999999999', '[':'(', '＆':'&'}
     line = ''.join(map_dict.get(c,c) for c in line)
     print line,

I experimented this with aaaa.txt but it's simply not replacing anything.

A simpler code that I know works is

import fileinput
for line in fileinput.FileInput("label(Nreplaced).txt",inplace=1):
    line = line.replace("\N","999999999")
    print line,

But I want to make the first code work, because it replaces multiple things.
