1，简单异常处理
try: date["name"] names[3] except (IndexError, KeyError) as e: print('检测IndexError/KeyError异常', e) except Exception as e: print('检测所有异常', e) else: print('一切正常') finally: print('有错无措，都执行')
2，自定义异常处理
# 自定义异常类，继承Exception class ElvaException(Exception): def __init__(self, msg): self.message = msg def __str__(self): return '测试测试' # return self.message try: raise ElvaException('数据库连接错误') # raise调用自己定义异常 except ElvaException as e: print(e)
