First, the HTTP exception handling problem. When Urlopen is not able to handle a response, Urlerror is generated. However, the usual Python APIs, such as Valueerror,typeerror, will also be generated at the same time. Httperror is a subclass of Urlerror, usually generated in a specific HTTP URLs. 1.URLError Typically, urlerror occurs when there is no network connection (no routing to a particular server), or if the server does not exist. In this case, the exception will also
