    class PooledDatabase(object):
        def __init__(self, database, max_connections=20, stale_timeout=None,
                     timeout=None, **kwargs):
            self._max_connections = make_int(max_connections)
            self._stale_timeout = make_int(stale_timeout)
            self._wait_timeout = make_int(timeout)
            if self._wait_timeout == 0:
                self._wait_timeout = float('inf')
    
            self._pool_lock = threading.RLock()
    
            # Available / idle connections stored in a heap, sorted oldest first.
            self._connections = []
    
            # Mapping of connection id to PoolConnection. Ordinarily we would want
            # to use something like a WeakKeyDictionary, but Python typically won't
            # allow us to create weak references to connection objects.
            self._in_use = {}
    
            # Use the memory address of the connection as the key in the event the
            # connection object is not hashable. Connections will not get
            # garbage-collected, however, because a reference to them will persist
            # in "_in_use" as long as the conn has not been closed.
            self.conn_key = id
    
            super(PooledDatabase, self).__init__(database, **kwargs)
    

    这里这种用法正确么? super(PooledDatabase, self).init(database, **kwargs)

    语法没有错误,意义就要看应该放在哪一行

    这是老版本用法

    现在只用 super().__init__()
