Python Rope: how to find all missing imports and errors in all refactorings of all modules

Question

I try to find all missing import statements and errors for each module and its modules.

Is there a special tool for what I'm trying to do?

The code I wrote, but it seems really awful and maybe something like this already exists:

import os
def find_missing_imports(walk):
    for items in walk:
        d = items[0]
        f_list = items[1]
        for f in f_list:
            module = f[:-3]
            # posix_path
            module_path = d.lstrip('.').replace('/','.').lstrip('.')
            try:
                __import__(module_path, fromlist=[module])
            except IndentationError, e:
                #print(f,e)
                pass
            except NameError, e:
                print(d,f,e)
                pass
            except Exception, e:
                print(f,e)
                pass

walk = [[root,files] for root,dirs,files in os.walk('.') for fn in files if  fn.endswith('.py')]
find_missing_imports(walk)

Outputs:

('./Sky_Group_Inventory_Scanner-wxpython/display_image/Dialogs', 'ImageSelectionFrame.py', NameError("name 'wx' is not defined",))
('./Sky_Group_Inventory_Scanner-wxpython/display_image/Dialogs', 'ItemSpecificsDialog.py', NameError("name 'wx' is not defined",))
('./Sky_Group_Inventory_Scanner-wxpython/display_image/Dialogs', 'ReturnCorrectWatchTitle.py', NameError("name 'wx' is not defined",))

My project before refactoring was a mess, but kind of useful, now it's broken after refactoring.

After reading the "Pragmatic Programmer" based on the sentences of my initial codereview post:
