Yes
it does work properly outside listcomps.

            canBusType = 'CANdiag'
            result1 = eval('canBusType')
            result2 = [eval('canBusType'), eval('canBusType'), eval(
'canBusType')]
            result3 = [eval('canBusType') for i in range(3)]

result1 = 'CANdiag'
result2 =['CANdiag' 'CANdiag' 'CANdiag']
for result3:
NameError: name 'canBusType' is not defined

[bpo-5242] eval() function in List Comprehension doesn't work

I can't reproduce it either, tested with Py3 (on Linux and Windows) and
with Py2.[456], it worked fine everywhere.

Does your eval() work properly outside listcomps?
