Passing multiple parameters to a Python method: the * tag

Posted by jpluimers on 2019/08/28

I had to pass parameters to a method so they became a list:

    threadManager.append(
        UrlMonitorThread(monitor, "http://%s" % targetHost),
        SmtpMonitorThread(monitor, targetHost, 25),
        SmtpMonitorThread(monitor, targetHost, 587),
        SshMonitorThread(monitor, targetHost, 22))

This appeared much easier than I anticipated:

    def append(self, *threads):
        for thread in threads:
            self.threads.append(thread)

It uses the * tag which is explained here:
