Python - Class Scope

I have a python class that works great.

However I need to replace a function from another class as part of my class.

class myclass:

   def display(self, jobid):   #Self here is referencing my class
       zoom = NavigationToolbar2.zoom
       def new_zoom(self, *args, **kwargs):
           if self.blurEnabled:    #Self is referencing NavigationToolbar2 Instance instead of my class
               self.toggleBlur()   #Self is referencing NavigationToolbar2 Instance instead of my class
           zoom(self, *args, **kwargs)
       NavigationToolbar2.zoom = new_zoom

The code here works great, except for I am unable to acces my own class so my own functions fail. Is anyone able to help??

The reason is that the variable self gets overloaded in your inner scope. Try renaming it, e.g.

class myclass:

   def display(self, jobid):   #Self here is referencing my class
       zoom = NavigationToolbar2.zoom
       def new_zoom(toolbar, *args, **kwargs):
          ...
       NavigationToolbar2.zoom = new_zoom
