为什么代码会导致CPU占用100%？

如下的代码，使我cpu的占用率达到100%，我的电脑是40核心的电脑，这样有问题吗？

from tqsdk import TqApi, TqAuth, TqSim, TqKq
api = TqApi(TqKq(), auth=TqAuth())
order = api.get_order()
position = api.get_position()
account = api.get_account()
while True:
    api.wait_update()
    if api.is_changing(position):
        print(position)
    if api.is_changing(account):
        print(account)
    if api.is_changing(order):
        print(order)
