I am using python-docx and I am able to generate number lists. How do I have the numbers restart for those lists?

I want the lists to look like this.

List 1

1. List 1 Item 1
2. List 1 Item 2
3. List 1 Item 3

List 2

1. List 2 Item 1
2. List 2 Item 2
3. List 3 Item 3

Python-docx generates the items like this

1. List 1 Item 1
2. List 1 Item 2
3. List 1 Item 3
4. List 2 Item 1
5. List 2 Item 2
6. List 3 Item 3

I would appreciate help with fixing this issue.
