However, I didn't actually answer your question.
As Kent has already mentioned, eval is quite dangerous in python and to
be avoided when possible. I think it would be safer to do something
like this:
l = locals()
for x, y in zip( varlist, data ):
l[x] = y
or, more tersely:
[ locals()[x] = y for x, y in zip( varlist, data ) ]
This will accomplish what you're trying to do, but a dict really gives
you greater functionality than assigning to local variables.
Python is *not* Matlab. Functions that have the same name are not
necessarily equivalent. Plus, you should start to "think in Python"
rather than "thinking in Matlab" and transliterating.
