Yves,

now, I don't know Python, but my guess is you're struggling with that 
query partially because of this bug:
http://mapserver.gis.umn.edu/bugs/show_bug.cgi?id=1948

I would expect the following to work, but then I might be overlooking 
some Python-specific stuff:

myLayer.queryByAttributes(mapobject, None, "\"ville='Paris'\"", 1)

What's tricky in Mapserver 4.10.0, is that you need to wrap the entire 
query in quotes due to the bug I mentioned above.

Best regards,
