"To Sherlock Holmes she is always THE woman. I have seldom heard"
" him mention her under any other name. In his eyes she eclipses"
" and predominates the whole of her sex. It was not that he felt"
" any emotion akin to love for Irene Adler. All emotions, and that"
" one particularly, were abhorrent to his cold, precise but"
" admirably balanced mind. He was, I take it, the most perfect"
" reasoning and observing machine that the world has seen, but as a"
" lover he would have placed himself in a false position. He never"
" spoke of the softer passions, save with a gibe and a sneer. They"
" were admirable things for the observer--excellent for drawing the"
" veil from men's motives and actions. But for the trained reasoner"
" to admit such intrusions into his own delicate and finely"
" adjusted temperament was to introduce a distracting factor which"
" might throw a doubt upon all his mental results. Grit in a"
" sensitive instrument, or a crack in one of his own high-power"
" lenses, would not be more disturbing than a strong emotion in a"
" nature such as his. And yet there was but one woman to him, and"
" that woman was the late Irene Adler, of dubious and questionable memory."

Examples
After applying borders to a paragraph, the default paragraph style is applied to the paragraph using Resetting Paragraph Style to Default.
Apply Border
Create a border around a paragraph.
Note that next paragraph has the same border properties because merge is the default behaviour.
# ... other code
cursor = Write.get_cursor(doc)
bdr = Borders(all=Side(line=BorderLineKind.DASH_DOT, color=CommonColor.BLUE_VIOLET))
Write.append_para(cursor=cursor, text=p_txt, styles=[bdr])
Write.append_para(cursor=cursor, text=p_txt)

When merge=False
the paragraphs have the same border properties but are not merged.
# ... other code
cursor = Write.get_cursor(doc)
bdr = Borders(all=Side(line=BorderLineKind.DASH_DOT, color=CommonColor.BLUE_VIOLET), merge=False)
Write.append_para(cursor=cursor, text=p_txt, styles=[bdr])
Write.append_para(cursor=cursor, text=p_txt)

Resetting for the next paragraph can be done by applying Para.default
to the cursor.
# ... other code
cursor = Write.get_cursor(doc)
bdr = Borders(all=Side(line=BorderLineKind.DASH_DOT, color=CommonColor.BLUE_VIOLET), merge=False)
Write.append_para(cursor=cursor, text=p_txt, styles=[bdr])
StylePara.default.apply(cursor)
Write.append_para(cursor=cursor, text=p_txt)

Apply Border With Shadow
# ... other code
cursor = Write.get_cursor(doc)
bdr = Borders(
all=Side(line=BorderLineKind.DASH_DOT, color=CommonColor.BLUE_VIOLET),
shadow=Shadow(),
merge=False,
)
Write.append_para(cursor=cursor, text=p_txt, styles=[bdr])
StylePara.default.apply(cursor)
Write.append_para(cursor=cursor, text=p_txt)

Apply Border With Shadow and Padding
# ... other code
cursor = Write.get_cursor(doc)
bdr = Borders(

padding=Padding(all=7.7),
shadow=Shadow(),
merge=False,
)
Write.append_para(cursor=cursor, text=p_txt, styles=[bdr])
StylePara.default.apply(cursor)
Write.append_para(cursor=cursor, text=p_txt)

Getting Borders from Paragraph
A paragraph cursor object is used to select the first paragraph in the document. The paragraph cursor is then used to get the style.
# ... other code
cursor = Write.get_cursor(doc)
bdr = Borders(
all=Side(line=BorderLineKind.DASH_DOT, color=CommonColor.BLUE_VIOLET),
padding=Padding(all=7.7),
shadow=Shadow(),
merge=False,
)
Write.append_para(cursor=cursor, text=p_txt, styles=[bdr])
para_cursor = Write.get_paragraph_cursor(cursor)
para_cursor.gotoPreviousParagraph(False)
para_cursor.gotoEndOfParagraph(True)
para_bdr = Borders.from_obj(para_cursor)
assert para_bdr.prop_inner_sides.prop_left.prop_line == BorderLineKind.DASH_DOT
assert para_bdr.prop_inner_sides.prop_right.prop_color == CommonColor.BLUE_VIOLET
StylePara.default.apply(cursor)
Write.append_para(cursor=cursor, text=p_txt)
