def add(self, list_template: aspose.words.lists.ListTemplate):
    ...

Parameter	Type	Description
list_template	ListTemplate	The template of the list.

Remarks

Aspose.Words list templates correspond to the 21 list templates available in the Bullets and Numbering dialog box in Microsoft Word 2003.

All lists created using this method have 9 list levels.

Returns

The newly created list.

add(list_style)

Creates a new list that references a list style and adds it to the collection of lists in the document.

def add(self, list_style: aspose.words.Style):
    ...

Parameter	Type	Description
list_style	Style	The list style.

Remarks

The newly created list references the list style. If you change the properties of the list style, it is reflected in the properties of the list. Vice versa, if you change the properties of the list, it is reflected in the properties of the list style.

Returns

The newly created list.

# A list allows us to organize and decorate sets of paragraphs with prefix symbols and indents.
# We can create nested lists by increasing the indent level.
# We can begin and end a list by using a document builder's "ListFormat" property.
# Each paragraph that we add between a list's start and the end will become an item in the list.
# Below are two types of lists that we can create using a document builder.
# 1 -  A numbered list:
# Numbered lists create a logical order for their paragraphs by numbering each item.

# to begin a self-contained sub-list at the current list item.
