Peewee - Database Errors

Pythons DB-API standard (recommended by PEP 249) specifies the types of Exception classes to be defined by any DB-API compliant module (such as pymysql, pyscopg2, etc.).

Peewee API provides easy-to-use wrappers for these exceptions. PeeweeException is the base classes from which following Exception classes has been defined in Peewee API −

• DatabaseError

• DataError

• IntegrityError

• InterfaceError

• InternalError

• NotSupportedError

• OperationalError

• ProgrammingError

Instead of DB-API specific exceptions to be tried, we can implement above ones from Peewee.
