你可以使用python-docx库来处理word文档。以下是一些常见的文本处理操作:
1.打开文档
```python
from docx import Document
doc = Document('example.docx') # 打开文档
```
2.读取文档中的段落
```python
for para in doc.paragraphs:
print(para.text) # 输出每个段落的文本内容
```
3.读取文档中的表格
```python
for table in doc.tables:
for row in table.rows:
for cell in row.cells:
print(cell.text) # 输出每个单元格的文本内容
```
4.向文档中添加段落
```python
from docx import Document
from docx.shared import Inches
doc = Document()
doc.add_paragraph('Hello, World!') # 添加一个段落
doc.add_picture('picture.jpg', width=Inches(1.25)) # 添加一张图片
doc.save('example.docx') # 保存文档
```
5.搜索文档中是否包含指定词汇,批量替换
```python
from docx import Document
doc = Document('example.docx')
for para in doc.paragraphs:
if 'old_text' in para.text:
para.text = para.text.replace('old_text', 'new_text') # 替换文本
doc.save('example.docx') # 保存文档
```
6.将文档中的一条线与中心对齐
```python
from docx import Document
from docx.enum.text import WD_ALIGN_PARAGRAPH
from docx.shared import Pt
doc = Document('example.docx')
for para in doc.paragraphs:
if 'line_text' in para.text:
para_format = para.paragraph_format
para_format.alignment = WD_ALIGN_PARAGRAPH.CENTER # 设置对齐方式为居中
run = para.add_run()
run.add_break()
run.add_break()
run.add_break()
run.add_break()
run.add_break()
run.add_break()
run.add_break()
run.add_break()
run.add_break()
run.add_break()
run.add_break()
run.add_break()
run.add_break()
run.add_break()
run.add_break()
run.add_break()
run.add_break()
run.add_break()
run.add_break()
run.add_break()
run.add_break()
run.add_break()
run.add_break() # 添加多个换行符,使得线条居中
run.add_text('------------------------') # 添加线条
run.font.size = Pt(12) # 设置字体大小
doc.save('example.docx') # 保存文档
```
