The following is a program to validate customer numbers.
```python
customer_number = input('Enter the employee number (dd-ddd-dddd): ')
parts = customer_number.split('-')
valid = False
if len(parts) == 3:
if parts[0].isdigit() and parts[1].isdigit() and parts[2].isdigit():
valid = True
print(valid)
```
The number may only contain numbers and dashes. The number must have the right format (dd-ddd-dddd).
What is true about this program?
