Python异常处理

# l = [1,2,3]
# d  = {"name":"11"}
# import traceback
# try:
#     name = d["name"]
#     # l[4]
# # except KeyError as e:
# #     print(e)
# #     print("出现异常了")
# # except IndexError as e:
# #     print("出现下标不存在的异常了")
# except Exception as e:
#     traceback.print_exc()
#     msg = traceback.format_exc()
#     print(msg)
# else:
#     print("没有出现异常")
# finally:
#     print("不管你出不出异常他都会走")
