I do not quite understand walk library function. Python Library
Reference says that walk calls function 'visit'. 

- What is visit's syntax? 
- Or does 'visit' stand for any external program, like 'ls -l'?
- If walk has parameters (path, visit, arg), what is the description of
parameters (arg, dirname, names) which are used for 'visit'?
