How to get rid of \r\n from a string?

I recently had to upgrade to Jython 2.7.2. I send in a Java map instance into my python script.

Previously my python script would print out the key, value in the map as in the below format

message: Community: public

This same string now appears as

u'message': u'Community:\t\tpublic\r

I managed to get rid of the u' prefix by doing the following

encode(encoding = 'UTF-8', errors = 'strict')

But am still left with the \t\r in the string

'message': 'Community:\t\tpublic\r

and it feels very clumsy to manually remove these from the string. Is there any good utility method that would help me to preserve the pre 2.7.7 handling of strings?

Normally the character \r comes from a windows' file and the easiest way to get rid of them is just use replace

mystring = u'asd\r'
mystring = mystring.replace("\r", "")
print(repr(mystring))

Gives the output:

u'asd'

Why not use the toString() method and then replace the unwanted characters?

Sample code:

import java.util.HashMap as HashMap
import re


def test_2():
    my_map = HashMap()
    inner_map = HashMap()
    inner_map.put("community", "public")
    my_map.put("message", inner_map)

    print re.sub(r"[{}]*", "", my_map.toString()).replace("=", ": ")


if __name__ == '__main__':
    test_2()

Output:
