If a pandas df column has a specific value, another column only allow a list of values

I have a dataframe that has a department, its function, its subfunction and its sub-subfunction. A example of the dataframe would be this:

       Department           Function      Subfunction   Sub-subfunction
0        Dept1                 HR          HR Talent        HR Talent 3
1        Dept2                 IT         Analysis HR      Analysis HR 2
2        Dept3                 IT          IT Support        IT Tech 2
3        Dept4                 HR           IT Tech         HR Talent 1               
4        Dept5                 MKT         IT Support      MKT Strategy 2
5        Dept6                 MKT         MKT Comm         MKT Comm2

I need to create a rule that would check if a department has a certain value in function, it only allow a possible list of values in subfunction. Then, in subfunction the same, each unique value would allow only a possible list of values in sub-subfunction.

It would work Like this:

• If the value in Function is HR, then the value accepted for Subfunction would be only the ones related to HR. Same for Marketing and IT.
• If the sunfunction then is correct, it would check if the sub-subfunction is valid (let's say that each subfunction can have their break down into 1, 2 and 3). So if, for example, the subfunction is "HR Talent", the sub-subfunction would only accept "HR Talent 1", "HR Talent 2" and "HR Talent 3".

In this dataframe, this function would return the ones that do not obey this rule, in this example it would return:

       Department           Function      Subfunction   Sub-subfunction
1        Dept2                 IT         Analysis HR      Analysis HR 2
2        Dept3                 IT          IT Support        IT Tech 2
3        Dept4                 HR           IT Tech         HR Talent 1               
4        Dept5                 MKT         IT Support      MKT Strategy 2

What would be the best way to apply those rules?

Thank you for the support!
