What does [,some_par] mean in python?

Looking through documentation I sometimes see a list of parameters containing par_n[,par x]. For example: str.center(width[, fillchar])

What does this mean? Any attempts of looking for answers using google and in stackoverflow have not been successful.

It marks an optional parameter. You can call mystring.center(42) as well as mystring.center(42, ' '). The function’s documentation should hint how the behavior would differ.
