我有一个持有字典的班级

class OrderBook:
    orders = {'Restaurant1': None,
              'Restaurant2': None,
              'Restaurant3': None,
              'Restaurant4': None}

    @staticmethod
    def addOrder(restaurant_name, orders):
        OrderBook.orders[restaurant_name] = orders

我正在运行调用该方法的4个线程(每个餐厅一个)OrderBook.addOrder.这是每个线程运行的函数:

def addOrders(restaurant_name):

    #creates orders
    ...

    OrderBook.addOrder(restaurant_name, orders)

这是安全的,还是我必须在打电话前使用锁addOrder？
