You haven't provided sufficient information about which bits you are 
willing to change.

Some things you could do are:

* use Cygwin Python
* change the Python script to output \n instead of \r\n
* [ $foo = $'True\r' ]
* [ ${foo/%$'\r'/} = True ]

The last has the advantage that it will work even if the script outputs 
only "True\n" instead of \r\n.
