Unfortunately, we have no idea what values are in ‘MYMAP’ nor ‘www’. So
it's difficult for us to see what might be causing any problem, or even
whether there is any problem.

Can you show a complete example which demonstrates that there is an
error? For example::
>>> import numpy
>>> map = numpy.array([10, 20, 30])
>>> map[1] + 4
24
Please show a simple, self-contained, correct example
<URL:http://sscce.org/> like the above, which demonstrates the
problematic behaviour.
You'll also need to be more descriptive of what you think the problem
is: What are you expecting? What are you experiencing instead?
