python使用docxtpl处理word文档图片不显示问题
docxtpl的使用：
安装docxtpl：
pip install docxtpl
基本使用实例main.py：
from docxtpl import DocxTemplate
doc = DocxTemplate("my_word_template.docx")
sd = doc.new_subdoc("my_subdoc.docx")
context = {
'company_name': "World company",
'sub_doc': sd,
}
doc.render(context)
doc.save("generated_doc.docx")
其中模板文件my_word_template.docx内容如下：
子文件my_subdoc.docx内容如下：
执行main.py生成generated_doc.docx文件
问题处理：
