python - 无法访问 Python 中的特定属性

Question

模块:https://github.com/yanagisawa-kentaro-777/pybitmex/blob/master/pybitmex/bitmex.py

我正在使用 ws_open_order_objects_of_account() 并使用它，我可以访问:

open_orders = bitmex.ws_open_order_objects_of_account()
for open_bid in open_orders.bids:
    print(open_bid.price)

但我想要 open_bid.orderID 并且我已经尝试过不可订阅的 open_bid['orderID']。我读的是只返回价格的函数吗？

Answer 1

当你遇到这种情况时，我建议你使用 Python 自省(introspection)工具，例如 dir(open_bid) 和 type(open_bid) 来找出你在做什么看着!

根据对源代码的快速阅读，我怀疑您正在查看

class OpenOrder:

    def __init__(self, order_id, client_order_id, side, quantity, price, timestamp):
        self.order_id = order_id
        self.client_order_id = client_order_id
        self.side = side
        self.quantity = quantity
        self.price = price
        self.timestamp = timestamp

    def __str__(self):
        return "Side: {}; Quantity: {:d}; Price: {:.1f}; OrderID: {}; ClOrdID: {}; Timestamp: {}; ".format(
            self.side, self.quantity, self.price, self.order_id, self.client_order_id,
            self.timestamp.strftime("%Y%m%d_%H%M%S")
        )

所以您可能需要 open_bid.order_id
