problem occurs with replaced values using fileinput

Hi All,

I am able to use urlib2 through proxy. I give proxy credentials and use
# Set the Proxy Address
proxy_ip = ""

proxy_user = 'senthil_or'
proxy_password = urllib.quote(proxy_password_orig,"")

# Setup the Proxy with urllib2

proxy_url = 'http://' + proxy_user + ':' + proxy_password + '@' +
#proxy_url = urllib.quote(proxy_url_add)
proxy_support = urllib2.ProxyHandler({"http":proxy_url})
opener = urllib2.build_opener(proxy_support,urllib2.HTTPHan dler)

Now, I have decided in my program, I shall give a Configfile.txt to
users who can enter the proxy details and I shall substitute the
details in the script;

#FILE: Configfile.txt
# Provide the Proxy Details
PROXY_USER: senthil_or

#Config Parsing function.

def configParsed():
"""Parse the Configfile.txt"""
configparser = ConfigParser()
settings = {}
settings['PROXY_IP'] = configparser.get('PROXY','PROXY_IP')
settings['PROXY_PORT'] =
settings['PROXY_USER'] = configparser.get('PROXY','PROXY_USER')
settings['PROXY_PASSWORD'] =
return settings

Now, in my script I do a replacement of values in the script:

FILE BEFORE Replacement:
# Set the Proxy Address
proxy_ip = "PROXY_IP:PROXY_PORT"

proxy_user = 'PROXY_USER'
proxy_password = urllib.quote(proxy_password_orig,"")
# Setup the Proxy with urllib2
proxy_url = 'http://' + proxy_user + ':' + proxy_password + '@' +
#proxy_url = urllib.quote(proxy_url_add)
proxy_support = urllib2.ProxyHandler({"http":proxy_url})
opener = urllib2.build_opener(proxy_support,urllib2.HTTPHan dler)

# Replacing Functions:
def replaceProxy(settings):
'''Replace the Proxy Credential values'''
for k,v in settings.items():
for line in fileinput.input('src' + os.sep+'file.py',inplace=1):
print line.replace(k,v),
The problem, I am facing is, when I use a script to replace certain
variables with config file based values, the urllib2 is failing!! It is
not able to get the correct credentials to open the proxy!
I debuged and derived at the conclusion at there is something wrong
with replaceProxy(settings) function I am using:
1) Either with for k,v in settings.items()
2) OR with fileinput.input and print line.replace(k,v),

The output file with replaced values looks perfectly fine to human
eyes! I dont know what is happening with automatic replacement of
values which is failing my program.

Has anyone faced this kind of scenario before?
Need your help in solving this.
