python异常处理错误RequestException

Question

我正在 python 应用程序中尝试 try catch 方法。我不确定我犯了什么错误，是缩进问题还是其他问题

这是我的代码。

try:

            ivurl = f'{api}/company/{id}/contacts?'

            payload: Dict[str, Union[bool, int]] = {'id': True}

            response = get_iv_response(url=ivurl, payload=payload)

            email_contact_totalresult: int = response.get('totalResults')

            email = int(email_contact_totalresult)

            payload: Dict[str, Union[bool, int]] = {'name': True}

            response = get_iv_response(url=ivurl, payload=payload)

            phone_contact_totalresult: int = response.get('totalResults')

            phone = int(phone_contact_totalresult)

            print ("here")

            if email > 0 or phone > 0:

                print (f"{id} has contacts")

                update_query = f"""update section 

                                set has_contact = true ,

                                updated = '{cur_date}'      

                            where name = '{id}'

                            """

                print(update_query)

                insert_query = f"""insert into quota(name,age)

                                values ('{name}',

                                        '{age}')"""

                print (insert_query)

                cursor.execute(update_query)

                cursor.execute(insert_query)

            

                conn.commit()

            else :

                print (f"{id} doesnot  has contacts")

        except:requests.RequestException as error1:

            print ("error1:",error1)

        # except requests.exceptions.HTTPError as error2:

        #     print ("error1:",error2)

        # except requests.exceptions.ConnectionError as error3:

        #     print ("error3:",error3)

        # except requests.exceptions.Timeout as error4:

        #     print ("error4:",error4)

    print ("job done")

    print(end_time)

    print('Duration: {}'.format(end_time - start_time))

我在“as”无效语法附近遇到错误

语法应该是这样的：try:    #this expression was not defined anywhere, hence the NameError    print(leromipsum) except NameError as error1:    print("meh")因此，在您的代码中，我认为您应该先删除标识：except:requests.RequestException as error1:    print ("error1:",error1)并在 except 后删除冒号：except requests.RequestException as error1:    print ("error1:",error1)干杯编辑：try:    print("this code runs")    raise requests.HTTPError    print("this code is skipped, if an error occurs")except requests.RequestException as error1:    print ("error1:",error1)except requests.exceptions.HTTPError as error2:    print ("error1:",error2)except requests.exceptions.ConnectionError as error3:    print ("error3:",error3)except requests.exceptions.Timeout as error4:    print ("error4:",error4)这个最小的例子对我有用。
