使用Python docx修改word关键词颜色的操作

from docx import Document
from docx.shared import Pt#设置字体
from docx.oxml.ns import qn#设置中文字体

i=0
document = Document()#新建word
p = document.add_paragraph('')#新建段落，这句话放在循环外面可以减少空行
while i<3190:
	content = f.readline()
	#print(content)
	
	if content.find('答案')!=-1: #如果该行有关键字“答案”就以关键字为分界进行分割
		pt = r'(答案)'
		res = re.split(pt, content)#分割
		#print(res[0],end=' ')
		#print(res[1],end=' ')
		#print(res[2])
		
		#add_run在同一段添加内容
		run = p.add_run(res[0])#输入关键字之前的字符
		run.font.name=u'宋体' #设置插入的字体
		run.font.size = Pt(15)
		r = run._element
		r.rPr.rFonts.set(qn('w:eastAsia'), u'宋体')
