# 模板方法模式 Template Method Pattern GeovinDuTemplate.template_function(GeovinDuTemplate.get_text, to_save=True) GeovinDuTemplate.template_function(GeovinDuTemplate.get_pdf, converter=GeovinDuTemplate.convert_to_text()) GeovinDuTemplate.template_function(GeovinDuTemplate.get_csv, to_save=True) GeovinDuTemplate.template_function(GeovinDuTemplate.get_xml, to_save=True)
输出：
得到为： `text 文件` 跳过转换 [SAVE] `text 文件` 进行处理中
