result.params is an ordered dictionary of Parameter objects, each of which has the best value stored in the value attribute, and several other attributes. Basically, fit_report does something like:

for param in result.params.values():
    print("%s:  %f +/- %f (init = %f)" % (param.name, param.value, param.stderr, param.init_value)

You can modify that any way you'd like.

Specific values can be accessed by using

result.params.get('variable_name').value

For example:

result.params.get('fwhm').value
