Python Data Science Basics Exporting Exporting to Excel

Why do I have to import the specific modules after importing openpyxl? Doesn't the initial import get all functions?

import openpyxl
from openpyxl import Workbook
from openpyxl.writer.excel import ExcelWriter
from openpyxl.cell import get_column_letter

In the above, are the other imports after the initial import even necessary?

I know you can import a function as a name to shorten it but this seems redundantly redundant.

It really is to shorten your code later on. This way, you don't need to write openpyxl.writer.excel.ExcelWriter every time you need that class. I could be wrong, but I believe python compiler is smart enough to not import multiple copies of the same class files, so you're not losing anything by doing this other than having a couple extra import statements at the top of your file. It's just for convenience.
