This group is for python language and standard library issues
so the Scipy modules are a wee bit out of our scope. There
are some users who might be able to help though. but you might
like to try on the SciPy forums too because there will be a
lot more users there.

Probably outside. Otherwise you are reading and writing to the same file
every time you call the function. That will make it slow and probably
overwrite all of your data each time too. Imagine using it inside a
loop. You'd end up with only the last iteration of the loop stored in
the file all the earlier calls would be lost!

I'm assuming inside for this one. Yu want your function to set up the
data then call fsolve then present back the results filtered or
formatted in some way. I assume...

This is the kind of thing that's probably better answered on the
Scipy forum(s)

We can help with those areas, but not so much with svcipy
module specific type issues.
