When running tests on Python 3.4.3 or 2.7.6 I pass the first test, then:

"Traceback (most recent call last):
File "main.py", line 23, in
Test.expect(results1.connected(8,9),True , "Finds Valid Path")
File "/runner/frameworks/python/cw-2.py", line 22, in expect
display('FAILED', message)
File "/runner/frameworks/python/cw-2.py", line 14, in display
type.upper(), mode.upper(), label, format_message(message)))
File "/runner/frameworks/python/cw-2.py", line 9, in format_message
return message.replace("\n", "<:LF:>")
AttributeError: 'bool' object has no attribute 'replace'"
