python - Best way to use split and strip

My function scrapes my servers for the command and outputs something along the lines of offset=1.3682 which metrics_emit uses to send to our metrics collector/visualizer, datadog.

What I need to do is strip off the offset= part because metrics_emit only wants the numerical value. What would be the best way of stripping offset= as well as calling strip() on i so that it gets rid of all newlines and trailing/leading whitespaces?

def check(self):
    output = sh.ntpq("-nc rv")
    out_list = output.split(",")
    for i in out_list:
        if "offset" in i:
            self.metrics_emit('ntp.offset', i)
            break
