我已经获得了书目ID的列表。我想通过这些数字来预订变量来删除事件。如何将列表中的元素传递给变量

output of bookids samples : ['BOOK:688045640', 'BOOK:688045641', 'BOOK:688045642', 'BOOK:688045643', 'BOOK:688045644', 'BOOK:688045645', 'BOOK:688045646', 'BOOK:688045647'] 

我可以删除与下列动作单一事件:

book = self.bids[0] 

如何我可以通过bookids列表元素预定变量?

你试过用“for”循环吗? 您是否还想将“BOOK:688045640”或“688045640”传递给“--objectId =”参数 – SunilT

在你当前的代码你正在做的:

book = self.bids[0] 
# ... 
arg_list.append(book) 

这相当于

arg_list.append(self.bids[0]) 

self.bids列表中arg_list列表追加单个项目。整个self.bids列表中添加到arg_list年底,使用.extend方法代替:

arg_list.extend(self.bids) 

另一种选择是使用+=赋值运算符将扩展现有的列表:

arg_list += self.bids 

顺便说一句,你的subprocess.call(["python", arg_list])有点奇怪。正如the docs所示,它应该是

subprocess.call(["python"] + arg_list) 

然而,这将是更有效导入UPNP_Client_Cmd_Line模块直接调用其功能。
