General Questions about Oracle Roles/Privileges

Question

Hi,
I have a few questions I'm hoping to get clarification on:
1 - Is there a view similar to DBA_SYS_PRIVS/DBA_TAB_PRIVS that shows which system privileges have been assigned to users/accounts ONLY, filtering out roles? If not, how would one go about obtaining this list?
2 - Is there a view similar to DBA_ROLE_PRIVS that shows also just shows which users have been assigned to which roles ONLY, again filtering out roles? If not, how would one go about obtaining this list? I assume some type of recursion has to be done here to flatten out the roles.
My end goal is this:
- List of all users and directly assigned system privileges only
- List of all users and directly assigned table/object privileges only
- List of all users and all roles (if role X contains role Y, this list should show user has role X and Y)
Many thanks!

1 - Is there a view similar to DBA_SYS_PRIVS/DBA_TAB_PRIVS that shows which system privileges have been assigned to users/accounts ONLY, filtering out roles? If not, how would one go about obtaining this list?
it's simple:
select grantee, privilege from dba_sys_privs where grantee in (select username from dba_users);
select grantee, owner, table_name, privilege from dba_tab_privs where grantee in (select username from dba_users);
2 - Is there a view similar to DBA_ROLE_PRIVS that shows also just shows which users have been assigned to which roles ONLY, again filtering out roles? If not, how would one go about obtaining this list? I assume some type of recursion has to be done here to flatten out the roles.
select grantee, granted_role from dba_role_privs where grantee in (select username from dba_users);
select grantee, granted_role from dba_role_privs where grantee in (select role from dba_roles);Hope this helps...
