       Special read-only attributes: :attr:`co_name` gives the function name;

-      arguments with default values); :attr:`co_nlocals` is the number of local
-      variables used by the function (including arguments); :attr:`co_varnames` is a

-      names); :attr:`co_cellvars` is a tuple containing the names of local variables
