**Understanding AttributeError in Python: A Case Study**

### Overview
In this educational case study, we're examining a common error encountered in Python programming: the `AttributeError`. Specifically, we'll look at an example error related to class attributes and importing modules, to help students and developers grasp how such errors occur and how they might be resolved.

### Error Scenario
The following text is a transcribed error encountered during the execution of a Python script.

```
loyee.:py"
Enter the employee name: Bri
Enter the employee ID number: 1123
Enter the employee shift number: 1
Enter the employee hourly pay rate: 12
Traceback (most recent call last):
File "/Users/briannacardenas/Downloads/CS202 MOD7 Brianna Cardenas/class Employee:.py", line 1, in <module>
from employee import Employee
File "/Users/briannacardenas/Downloads/CS202 MOD7 Brianna Cardenas/employee.py", line 42, in <module>
main()
File "/Users/briannacardenas/Downloads/CS202 MOD7 Brianna Cardenas/employee.py", line 36, in main
wrk = Employee.ProductionWorker(Employee_name, Employee_id, Employee_shift,Employee_pay)
AttributeError: type object 'Employee' has no attribute 'ProductionWorker'
(base) briannacardenas@Briannas-Air CS202 MOD7 Brianna Cardenas %
```

### Error Breakdown

1. **User Input Section:**
```plaintext
Enter the employee name: Bri
Enter the employee ID number: 1123
Enter the employee shift number: 1
Enter the employee hourly pay rate: 12
```

The user is prompted to enter the employee's details, which are then captured by the script for processing.

2. **Traceback Details:**
The error traceback helps identify the source of the problem:
```plaintext
Traceback (most recent call last):
File "/Users/briannacardenas/Downloads/CS202 MOD7 Brianna Cardenas/class Employee:.py", line 1, in <module>
from employee import Employee
File "/Users/briannacardenas/Downloads/CS202 MOD7 Brianna Cardenas/employee.py", line 42, in <module>
