本文实例分析了Python docx库用法。分享给大家供大家参考，具体如下：
打开及保存文件：
from docx import Document
document = Document('test.docx')
document.save('test.docx')
添加文本：
document.add_paragraph('test text')
调整文本位置格式为居中：
from docx import Document
from docx.enum.text import WD_ALIGN_PARAGRAPH
document = Document('test.docx')
paragraph = document.add_paragraph('123')
paragraph.paragraph_format.alignment = WD_ALIGN_PARAGRAPH.CENTER
document.save('test.docx')
调整左缩进0.3英寸：
document = Document('test.docx')
paragraph = document.add_paragraph('this is test for left_indent with inches')
paragraph_format = paragraph.paragraph_format
paragraph_format.left_indent = Inches(0.3)
document.save('test.docx')
首行缩进：
paragraph_format.first_line_indent = Inches(0.3)
上行间距：
paragraph_format.space_before = Pt(18)
下行间距：
paragraph_format.space_after = Pt(12)
行距：
paragraph_format.line_spacing = Pt(18)
分页格式：
紧跟上段：
paragraph_format.keep_together
若本页无法完全显示，另起一页：
paragraph_format.keep_with_next
强制另起一页：
paragraph_format.page_break_before
字体格式：
p = document.add_paragraph()
run = p.add_run('test typeface')
#加粗
run.font.bold = True
#斜体
run.font.italic = True
#下划线
run.font.underline = True
WD_UNDERLINE 中有所有下划线格式
调用样例：
run.underline = WD_UNDERLINE.DOT_DASH
字体颜色：
from docx.shared import RGBColor
test = document.add_paragraph().add_run('color')
font = test.font
font.color.rgb = RGBColor(0x42, 0x24 , 0xE9)
调用预设颜色：
from docx.enum.dml import MSO_THEME_COLOR
font.color.theme_color = MSO_THEME_COLOR.ACCENT_1
