Typically for fitting you can use scipy.optimize functions, or lmfit which simply extends the scipy.optimize package to make it easier to pass things like bounds. Personally, I like using kmpfit, part of the kapteyn library and is based on the C implementation of MPFIT.

scipy.optimize.minimize() is probably the most easy to obtain and is commonly used.
