Find out emps reporting to same level hierarchy or lower-level hierarchy or superior-level hierarchy – python

Question

I’ve a table which has emp_id, emp_desg, and mgr_id. I’m trying to find and print the employees who are reporting to lower-level hierarchy or same level hierarchy or superior-level hierarchy.
I have a mapping for the hierarchy levels and a mapping to find opposing role reporting, if the cases in 2nd MAPPING matches in the table, then it should print it.

1st MAPPING (Hierarchy Levels)

2nd MAPPING (Opposing role) – These records need to be printed.

I need to iterate through each employee and their managers. If the levels of emp and mgr matches with the 2nd mapping, I need to print it. Please help me to solve this, thanks in advance.

emp_id	emp_desg	mgr_id
111	ASM	112
112	ASM	116
113	BSM	114
114	CSM	115
115	ASM	116
116	DSM	117

Expected output:

df['emp_role'] = df['emp_desg'].map(hrchy_levels) 
df['mgr_role'] = df['mgr_desg'].map(hrchy_levels)

Is there a way to compare ’emp_role’ and ‘mgr_role’ with ranks_subords and just print the emp_id and mgr_id. I need not want to change anything in df, So after printing, I’ll remove the added new columns emp_role and mgr_role. Thanks!

We start with defining the needed mappings for hierarchy and subordination.

hrchy_levels = {'ASM':'L1', 'BSM':'L2', 'CSM':'L3', 'DSM':'L4'}
ranks_subords = [('L1' , 'L1'),('L1' , 'L4'),('L2' , 'L1'),('L2' , 'L2'),('L3' , 'L3'),('L3' , 'L1'),('L3' , 'L2'),('L4' , 'L1'),('L4' , 'L2'),('L4' , 'L3')]

Then map manager ids to employee ids:

df['mgr_desg'] = df['mgr_id'].map(dict(df[['emp_id', 'emp_desg']].values))

Making replacements for level descriptions into another df and filtering by rank relations:

df2 = df.replace({'emp_desg': hrchy_levels, 'mgr_desg': hrchy_levels})
df2[df2.apply(lambda x: (x['emp_desg'], x['mgr_desg']) in ranks_subords, axis=1)]

   emp_id emp_desg  mgr_id mgr_desg
0     111       L1     112       L1
1     112       L1     116       L4
3     114       L3     115       L1
4     115       L1     116       L4

Now, it’s easy to iterate over the rows and print a formatted output.
