python函数执行顺序_python下for循环接if判断的函数执行顺序

如题,程序第4行开始,for循环接if判断,之后的name=self._nic_ovs_name_pattern.search(o) 指的是if条件判断返回true才执行赋值操作吗?还是if返回False执行的呢?最后一行的return ovs_nics,是什么条件满足后返回的呢?这个函数的整体执行顺序看的不是太明白,还请指教,谢谢.

def __extract_ovs_nic_detail(self, output):

ovs_nics = []

ovs_nic = {}

for o in output.split('\n'):

if '_uuid : ' in o:

ovs_nic = {}

name = self._nic_ovs_name_pattern.search(o)

if not name is None:

ovs_nic['name'] = name.group(2).strip('\"')

mac = self._nic_ovs_mac_pattern.search(o)

if not mac is None:

ovs_nic['mac'] = mac.group(2).strip('\"')

mtu = self._nic_ovs_mtu_pattern.search(o)

if not mtu is None:

ovs_nic['mtu'] = mtu.group(2)

speed = self._nic_ovs_speed_pattern.search(o)

if not speed is None:

ovs_nic['speed'] = str(int(speed.group(2)) / 1000000) + 'Mb/s'

if 'type : ' in o:

ovs_nics.append(ovs_nic)

return ovs_nics
