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.
