非Python程序猿 问个代码上的问题

ProxyPool/lib/proxybroker/providers.py

Line 115 in 9845049

self.proxies = received

        oldcount = len(self.proxies)
        try:
            received = self.find_proxies(page)
        except Exception as e:
            received = []
            log.error(
                'Error when executing find_proxies.'
                'Domain: %s; Error: %r' % (self.domain, e)
            )
        self.proxies = received

我的理解 received = self.find_proxies(page) 从当前页找到代理，然后 self.proxies = received 赋值给了实例的proxies属性，看起来是第1页找到10个，len(self.proxies)=10，然后第2页找到20个，赋值一下，len(self.proxies)=20了，但实际执行情况又不是，self.proxies是合并的结果，所以合并数组的代码在哪？

这个我没有具体跟踪过他的代码，可以尝试打个断点看看
