Python使用enum比较枚举

import enum
 
 
class BugStatus(enum.Enum):
 
    new = 7
    incomplete = 6
    invalid = 5
    wont_fix = 4
    in_progress = 3
    fix_committed = 2
    fix_released = 1
 
 
actual_state = BugStatus.wont_fix
desired_state = BugStatus.fix_released
 
print('Equality:',
      actual_state == desired_state,
      actual_state == BugStatus.wont_fix)
print('Identity:',
      actual_state is desired_state,
      actual_state is BugStatus.wont_fix)
print('Ordered by value:')
try:
    print('\n'.join('  ' + s.name for s in sorted(BugStatus)))
except TypeError as err:
    print('  Cannot sort: {}'.format(err))
    
# output
# Equality: False True
# Identity: False True
# Ordered by value:
#   Cannot sort: '<' not supported between instances of 'BugStatus' and 'BugStatus'
