ODB commands and editing ODB Files

I am currently trying to learn python scripting for ABAQUS. I have been running into to some issues with opening and accessing ODB files. I have noticed that in scripting examples there is always an "*" placed after import. Should I leave this syntax or should this be replaced with the pathway to the file I am trying to open? Also is there a library, in python, I should be installing before trying to use ODB specific commands? Thank you for the help in advance.
