It's a good idea to use "print" instead of a destructive command like 
"os.remove" until print displays the correct filenames :^)
Also, "list" and "file" are Python built-ins, so avoid using those names in 
code.

  import os,fnmatch
  patterns = '*.ini *.db'.split()
  for root,dirs,files in os.walk('/home/saad'):
    for pattern in patterns:
      for file_ in fnmatch.filter(files,pattern):
        print os.path.join(root,file_)
