Before you begin automating the cleaning of employee name lists, it is important to recall some useful string methods in Python. When dealing with inconsistent capitalization and unwanted spaces in names, you can use the `strip()` method to remove leading and trailing spaces, and the `title()` method to ensure each word in the name is properly capitalized.

name = "   jAnE doE   "
cleaned_name = name.strip().title()
print(cleaned_name)  # Output: Jane Doe

To process a list of employee names, you should apply both `strip()` and `title()` to each item in the list. This will ensure that every name is formatted consistently, making your HR records cleaner and easier to use in automated workflows.
