我有以下代码：
some = {}
stat = {'matches_played': 0, 'won': 0, 'draws': 0, 'loss': 0, 'points': 0}
some = {'Arsenal': stat}
some.update({'Chelsea': stat})
some['Arsenal']['won'] += 1
some['Chelsea']['loss'] += 1
print(some)
结果是：
{'Arsenal': {'matches_played': 0, 'won': 1, 'draws': 0, 'loss': 1, 'points': 0},
'Chelsea': {'matches_played': 0, 'won': 1, 'draws': 0, 'loss': 1, 'points': 0}}
但是我需要
{'Arsenal': {'matches_played': 0, 'won': 1, 'draws': 0, 'loss': 0, 'points': 0},
'Chelsea': {'matches_played': 0, 'won': 0, 'draws': 0, 'loss': 1, 'points': 0}}
您能解释一下为什么会发生这种情况吗？
