Python爬虫代码调试：namePrint函数为什么不打印内容？

{"title":"def parse_item(self, response):\n item = {}\n self.namePrint(response)\n self.handle_response_to_item(response)\n return item\n \n def namePrint(self, response):\n print('name:' + response.url)\nnamePrint函数为什么没有打印内容：The namePrint function is not printing because it is not being called in the parse_item function or anywhere else in the code. In order for the function to print, it needs to be called explicitly."}
