处理Firebase和#x27；url'；超过最大重试次数；Python中的错误

我一直在使用PythonFirebase库通过包中的POST方法将一些数据上传到我的实时数据库。在一些上传了以下错误的“产品”出现后，我已经尝试在每篇文章之间等待几秒钟

这是我到目前为止的代码：

导入json
从firebase导入firebase
进口稀土
从时间上导入睡眠
firebase=firebase.FirebaseApplication（'website\u url'）
如果uuuu name uuuuuu='\uuuuuuu main\uuuuuuu'：
以open（'./coto_scraper/data.json'）作为文件：
data=json.load（文件）
产品=[]
对于数据中的页面：
名称=第[“名称”]
价格=第[“价格”]
铁路超高名称=长度（名称）
不能_价格=len（价格）
打印（“铁路超高名称：”+str（铁路超高名称））
打印（“铁路超高价格：”+str（铁路超高价格））
铁路超高产品=铁路超高名称
做出改变=错误
如果铁路超高价格<铁路超高名称：
cant_产品=cant_价格
使改变为真
适用于范围内的i（cant_产品）：
true_name=re.sub（'+'，''，名称[i]。替换（'\n'，''）。替换（'\r'，''）。替换（'\t'，''）.rstrip（）
true\u name=re.sub（“（\）+”，“”，true\u name）
product={'name'：true\u name，'price'：prices[i]。替换（'\n'，''）。替换（'\r'，''）。替换（'\t'，''）}
products.append（产品）
firebase.post（'/products'，product）
印刷品（产品）
如果进行更改：
产品={'name'：名称[cant_names-1]，'price'：-1}
将open（'products.json'，'w'，encoding='utf-8'）作为json\u文件：
dump（产品，json文件，确保ascii=False）
