Python uses Python docx to insert formulas, tables, and charts into Word documents
Environmental construction and preparation work:
1. Install Python: First, you need to install a Python interpreter. You can download the latest version of Python from the official Python website and follow the installation steps.
2. Install the Python docx library: In the Python environment, use the pip command to install the Python docx library. You can run the following command from the command prompt to install it:
pip install python-docx
Dependent class libraries:
-Python docx: This is a Python library used to create, modify, and read Microsoft Word documents.
Complete sample and code:
The following is a complete example and code for inserting formulas, tables, and charts into Word documents using the Python docx library.
python
#Import the required library
from docx import Document
from docx.shared import Inches
from docx.enum.text import WD_PARAGRAPH_ALIGNMENT
from docx.oxml import OxmlElement
from docx.oxml.ns import nsdecls
from docx.oxml import parse_xml
from docx.oxml.text.paragraph import CT_P
from docx.oxml.table import CT_Tbl
#Create a new Word document
doc = Document()
#Insert Formula
def insert_formula(para, formula):
#Create a paragraph
p = doc.add_paragraph()
#Define the namespace of the formula
ns = 'w'
nsmap = {ns: nsdecls('w')}
#Create an OMath object
o_math = OxmlElement('m:oMath')
o_math = parse_xml(o_math.xml, nsmap=nsmap)
#Create an OMathPara object
o_math_para = OxmlElement('m:oMathPara')
o_math_para = parse_xml(o_math_para.xml, nsmap=nsmap)
#Create an OMathR object
o_math_run = OxmlElement('m:r')
o_math_run = parse_xml(o_math_run.xml, nsmap=nsmap)
#Create an OMath object
o_math_text = OxmlElement('m:t')
o_math_text = parse_xml(o_math_text.xml, nsmap=nsmap)
o_math_text.text = formula
o_math_run.append(o_math_text)
#Add OMathR object to OMathPara object
o_math_para.append(o_math_run)
#Add OMathPara object to OMath object
o_math.append(o_math_para)
#Add OMath object to paragraph
p._p.append(o_math)
#Add paragraphs to the document
para.add_run().add_paragraph()
#Insert Table
def insert_table():
#Create a table
table = doc.add_table(rows=3, cols=3)
#Traverse each cell in the table
for i in range(3):
for j in range(3):
cell = table.cell(i, j)
cell.text = f"Cell {i+1}-{j+1}"
#Set Table Style
table.style = "Table Grid"
#Insert Chart
def insert_chart():
#Create a chart
chart = doc.add_chart("bar", xlsx_path=None)
#Add data
data = [['A', 'B', 'C'], [1, 2, 3]]
chart.add_series("Series 1", data)
#Set Chart Title
chart.has_title = True
chart.chart_title.text = "Sample Chart"
#Add a chart to the document
doc.add_paragraph().add_run().add_chart(chart)
#Insert Formula
Heading=doc. add_ Heading ('Formula example ', level=1)
insert_formula(heading, "a^2 + b^2 = c^2")
#Insert Table
Heading=doc. add_ Heading ('Table example ', level=1)
insert_table()
#Insert Chart
Heading=doc. add_ Heading ('Chart example ', level=1)
insert_chart()
#Save Document
doc.save('sample.docx')
Print ("Word document has been generated and saved successfully!")
Summary:
The Python docx library makes it easy to manipulate Word documents and insert formulas, tables, and charts. Through our understanding of the library, we can use Python to automate the creation and modification of Word documents, achieving more efficient workflows.
