[Python]json 错误xx is not JSON serializable
TypeError: Decimal('1457501') is not JSON serializable
在使用json的时候经常会遇到xxx is not JSON serializable,也就是无法序列化某些对象
import decimal
class DecimalEncoder(json.JSONEncoder):
def default(self, o):
if isinstance(o, decimal.Decimal):
return float(o)
super(DecimalEncoder, self).default(o)
# and then:
json.dumps(chart_list,..., cls=DecimalEncoder)
