How is my list assignment is out of range?

October 24, 2022

I’m new to python and trying to understand 2D arrays. I’m trying to write a code in which someone inputs and stores the employee ID, department, and salary for 10 employees. Which is then stored using a 2D array The following will be outputted:

All the information with the appropriate column title
How many employees are working in each department Output it with the
department name
Input the department as accounts, admin and sales

This is my code:

EmpID = ""
Departement = ""
Salary = ""
EmpDetails = [[0 for c in range(3)] for r in range(4)]
for r in range(4):
    EmpDetails[r][1]=(input("Enter the Employee ID: "))
    EmpDetails[r][2]=(input("Enter the Department: "))
    EmpDetails[r][3]=int(input("Enter the Salary: "))
print("Employee ID     Department     Salary")
for r in range(4):
    for c in range(3):
        print(EmpDetails[r][c], end = " ")
        print() #??
        Account=0
        Adcount=0
        Scount=0
        for r in range(4):
            if EmpDetails[r][2] == "Accounts":
                Accounts=Account+1
            elif EmpDetails[r][2] == "Admin":
                Adcount=Adcount+1
            else:
                Scount=Scount+1
            print("Account: ", Account, "Employees")
            print("Admin: ", Adcount, "Employees")
            print("Sales: ", Scount, "Employees")

When I’m running the module, and error comes out at:

Enter the Employee ID: 1
Enter the Department: Accounts
Enter the Salary: 1000
Traceback (most recent call last):
  File "/Users/Documents/2darray.py", line 8, in <module>
    EmpDetails[r][3]=int(input("Enter the Salary: "))
IndexError: list assignment index out of range

I’m so confused as to how my list assignment is out of range? I can’t get past this so can’t continue on. Thank you in advance!
