day10 python operation word file

First, the basic content of the word document

Note: Install python-docx when installing third-party libraries

from docx import Document   # Import third-party libraries

1. Create a blank Word document

doc = Document()

2. Add a title

Document object.add_heading( title content, level=level, style=None) Note: Level range: 0~9

doc.add_heading('first level title',level=1)
doc.add_heading('secondary title', level=2)
...

3. Add body paragraphs

Document object.add_paragraph( text content, style=None)

doc.add_paragraph('Text content')

4. Add a page break

document object.add_page_break()

doc.add_page_break()

5. Add form

Document object.add_table( number of rows, number of columns) - add a table

table = doc.add_table(3, 4)  # Add a table with 3 rows and 4 columns

TableObject.cell( row subscript, column subscript) - get the specified cell in the table

cell1 = table.cell(0, 0)   # Get the cell at (0,0) position

cell object.text = data - modify cell content

cell1.text = 'Name'        # Modify the obtained cell1 cell content

6. Add pictures

Document object.add_picture( image address, width=None, height=None)

doc.add_picture('files/xxx.png')

save

doc.save('files/demo1.docx')

2. Set the style of the content in the document

from docx import Document    # Import third-party libraries
from docx.shared import Pt, Cm, RGBColor
from docx.enum.text import WD_PARAGRAPH_ALIGNMENT
from docx.oxml.ns import qn

Note: Style setting priority issues: document < paragraph < heading < run

doc = Document()
h1 = doc.add_heading('Why did Gao Qiqiang take off his tie and wipe the glass?', level=1)

1. Commonly used styles for titles

Center the title content in the document

h1.paragraph_format.alignment = WD_PARAGRAPH_ALIGNMENT.CENTER

Set the font size of the title

h1.style.font.size = Pt(25)

Set the text color of the title

h1.style.font.color.rgb = RGBColor(95, 158, 160)
# Note: Title setting font name is invalid

2. Commonly used paragraph styles

Note: The style set on a certain paragraph will affect all paragraphs at the same time.

p1 = doc.add_paragraph('Why did Gao Qiqiang take off his tie and wipe the glass during the second hurricane? There's a silent scene where nothing is said and everything is said)

1. Set the font name

p1.style.font.name = 'Times New Roman'

# Note: If the font used is a Chinese font, the following code must be added
r = p1.style._element.rPr.rFonts
r.set(qn('w:eastAsia'), 'Times New Roman')

2. Set the font size

p1.style.font.size = Pt(15)

3. Set font color

p1.style.font.color.rgb = RGBColor(255, 0, 0)

4. Set font bold

p1.style.font.bold = True

5. Slanted fonts

p1.style.font.italic = True

6. Add underline

p1.style.font.underline = True

7. Add strikethrough

p1.style.font.strike = True

8. Add a shadow effect

p1.style.font.shadow = True

3. The usage of run

There are two ways to provide text content to word documents:

1. Provide text content directly: doc.add_paragraph (text content), doc.add_heading (text content)

1. Provide text content through the run object

h2 = doc.add_heading(level=2)
run1 = h2.add_run('everyone is searching')
run2 = h2.add_run('"Gao Qiqiang"')

p2 = doc.add_paragraph()
run3 = p2.add_run('You can smash the glass and hit him if you untie your tie, or you can be like him')
run4 = p2.add_run('wipe the glass')
run5 = p2.add_run('. Zhao Lidong also understood what Gao Qiqiang meant, and at first thought he was going to beat him')

run4.font.bold = True
run3.font.color.rgb = RGBColor(0, 255, 0)

p3 = doc.add_paragraph('My brother's death is an eternal pain in my heart.')

4. Paragraph spacing related styles

Note: Paragraph spacing related styles will only be applied to the current paragraph

h3 = doc.add_heading('wipe the glass', level=2)
p4 = doc.add_paragraph('If you untie your tie, you can smash the glass and hit him, or you can clean the glass like him. Zhao Lidong also understood')

1. Line spacing (within a paragraph)

p4.paragraph_format.line_spacing = 1.5

2. Distance before paragraph

p4.paragraph_format.space_before = Pt(30)

3. Distance after paragraph

p4.paragraph_format.space_after = Pt(40)

4. Indent the beginning of the line

p4.paragraph_format.first_line_indent = Pt(50)

h4 = doc.add_heading('Cabo 2', level=2)

doc.save('files/demo2.docx')  # save

3. Set the theme style

from docx import Document
from docx.enum.style import WD_STYLE_TYPE, WD_BUILTIN_STYLE
from docx.shared import Pt, Cm, RGBColor   # Third-party libraries to be imported

doc = Document()

styles = doc.styles     #  all theme styles

There are three theme styles: run-based style, paragraph-based, table-based

1. Use of run-based theme styles

1. Usage

h1 = doc.add_heading(level=1)
run1 = h1.add_run('hello world!', style='Subtle Reference')
run1.font.size = Pt(40)

p1 = doc.add_paragraph()
p1.add_run('hello world!', style='Subtle Emphasis')


doc.add_heading('1. based on run The styles corresponding to all the theme names added:')

2. Display all theme styles related to run

for x in styles:
    if x.type == WD_STYLE_TYPE.CHARACTER:
        p = doc.add_paragraph()
        p.add_run('character(run) style is :'+ x.name,style = x.name)

2. Usage of theme style based on paragraph

p2 = doc.add_paragraph('My brother's death is an eternal pain in my heart',style='Title')
doc.add_heading('2. based on paragraph The styles corresponding to all the theme names added:')
for x in styles:
    if x.type == WD_STYLE_TYPE.PARAGRAPH:
        doc.add_paragraph('paragraph style is:'+x.name,style=x.name)

3. Usage of table-based themes

doc.add_table(4, 3, style='Medium Grid 3 Accent 4')

doc.add_heading('2.based on table The styles corresponding to all the theme names added:')
for x in styles:
    if x.type == WD_STYLE_TYPE.TABLE:
        p = doc.add_paragrapf('Form subject name:'+ x.name)
        p.paragraph_format.space_before = Pt(50)
        doc.add_table(2,3,style=x.name)

doc.save('files/demo3.docx')   # save

4. Use of forms

from docx import Document    # Third-party libraries to be imported
from docx.shared import Pt, RGBColor
from docx.enum.text import WD_PARAGRAPH_ALIGNMENT
from docx.enum.table import WD_CELL_VERTICAL_ALIGNMENT

doc = Document()

1. Add form

table = doc.add_table(3,4,style='Table Grid')

2. Add rows and columns

table.add_row()  # Add a line at the bottom

table.add_column(Pt(100))  # Add a column on the far right with a width of 100 pixels

3. Set cell content

1. Directly assign values ​​​​to the cell content

cell1 = table.cell(0,0)
cell1.text = 'name'
cell1.vertical_alignment = WD_CELL_VERTICAL_ALIGNMENT.CENTER

2. Add run to assign value by getting the paragraph object of the cell

cell2 = table.cell(0,1)
p = cell2.paragraphs[0]
run1 = p.add_run('price')
run2 = p.add_run('(Yuan)')

4. Set the table style

1. Directly set the table style, which will affect the entire table

table.style.font.size = Pt(14)
table.style.font.color.rgb = RGBColor(100,89,10)
table.style.paragraph_format.alignment = WD_PARAGRAPH_ALIGNMENT.CENTER

2. To set the style based on the cell, it must be set based on the run object corresponding to the cell content

run1.font.color.rgb = RGBColor(255, 0, 0)

5. Row height and column width

1. Set the height of each row

rows = table.rows       # get all rows
cols = table.columns    # get all columns

for row in rows:
    # get all cells
    print(row._cells)
    row.cells[1].text = '200'
    # Get row subscript
    print(row._index)
    if row._index == 0:
        # Set row height: row object.height = height
        row.height = Pt(40)
        for cell in row.cells:
            cell.vertical_alignment = WD_CELL_VERTICAL_ALIGNMENT.CENTER
    else: 
    	row.height = Pt(25)
        
        
for col in cols:
    # Get all cells in a column
    print(col.cells)
    col.cell[0].text = 'hello'
    # get column subscript
    print(col._index)

doc.save('files/demo4.docx')
