python: Fix unknown params and proxy multiplication

One of the recent changes made params not visible anymore:
    NameError: global name 'params' is not defined
This is fixed by adding the proper import statement.

However, the second error makes the multiplication values be assigned
to other proxies (that are not even used on the multiplication). A
workaround is added to prevent this from happening by extending "*=".
