How do I write a function to print out a hierarchy tree of the employees

Given a list of employees and their bosses as a csv file , write a function that will print out a hierarchy tree of the employees.

Sample input = Sam, Ian, technical lead, 2009 / Ian, NULL, CEO,2007/ Fred, Sam, developer, 2010

The format is name, supervisor, designation, year of joining

The output should be

Ian CEO 2007

-Sam Technical lead 2009

--Fred Developer 2010

What I have tried:

Python

import csv
with open("list.csv", 'r') as csv_file:
list_reader = csv.reader(csv_file, delimiter=",")
employee_list = {
    name: boss.strip() for name, boss, designation, year in list_reader}
mgrs = [k for k, v in employee_list.items() if v == '']
while mgrs:
    print ", ".join(mgrs)
    mgrs = [k for k, v in employee_list.items() if v in mgrs]

name: boss.strip() for name, boss, designation, year in list_reader}
ValueError: too many values to unpack

I cannot quite figure out what that code is supposed to do. however I think you should be using string.split[^], not string.strip[^].

C#

strq = "Sam, Ian, technical lead, 2009 / Ian, NULL, CEO,2007/Fred, Sam, developer, 2010"
def treeEmployee(infoStr):
	str1 = infoStr.split("/")
	s2 = []
	for i in str1:
		s2.append(i.split(","))
	for i in range(len(s2)):
		for j in range(1, len(s2)):
			if s2[i][1] == s2[j][0]:
				s2[i], s2[j] = s2[j], s2[i]
	return s2

Can we do it this way?
