list property

ListFormat.list property

Gets or sets the list this paragraph is a member of.

@property
def list(self) -> aspose.words.lists.List:
    ...

@list.setter
def list(self, value: aspose.words.lists.List):
    ...

Remarks

The list that is being assigned to this property must belong to the current document.

The list that is being assigned to this property must not be a list style definition.

Setting this property to None removes bullets and numbering from the paragraph and sets the list level number to zero. Setting this property to None is equivalent to calling ListFormat.remove_numbers().

Examples

Shows how to work with list levels.

doc = aw.Document()
builder = aw.DocumentBuilder(doc=doc)
self.assertFalse(builder.list_format.is_list_item)
# 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.
builder.list_format.list = doc.lists.add(list_template=aw.lists.ListTemplate.NUMBER_DEFAULT)
self.assertTrue(builder.list_format.is_list_item)
# By setting the "ListLevelNumber" property, we can increase the list level
# to begin a self-contained sub-list at the current list item.
# The Microsoft Word list template called "NumberDefault" uses numbers to create list levels for the first list level.
# Deeper list levels use letters and lowercase Roman numerals.
i = 0
while i < 9:
    builder.list_format.list_level_number = i
    builder.writeln('Level ' + str(i))
    i += 1
# 2 -  A bulleted list:
# This list will apply an indent and a bullet symbol ("•") before each paragraph.
# Deeper levels of this list will use different symbols, such as "■" and "○".
builder.list_format.list = doc.lists.add(list_template=aw.lists.ListTemplate.BULLET_DEFAULT)
i = 0
while i < 9:
    builder.list_format.list_level_number = i
    builder.writeln('Level ' + str(i))
    i += 1
# We can disable list formatting to not format any subsequent paragraphs as lists by un-setting the "List" flag.
builder.list_format.list = None
self.assertFalse(builder.list_format.is_list_item)
doc.save(file_name=ARTIFACTS_DIR + 'Lists.SpecifyListLevel.docx')
