Python Multithreading get child thread task return value

Today I want to implement multi-threaded update asset information, so used to threading, but I need the return value of each thread, which requires me in threading. The thread is encapsulated on the basis of

def auto_asset (node): ret = salt.remote_grains_execution_sigle (node) asset_info={} asset_info[' os ']= ret[node][' O Scodename '] asset_info[' kernelrelease ']= ret[node][' kernelrelease '] asset_info[' Cpu_model ']= ret[node][' Cpu_model ' ] asset_info[' DNS ']= ', '. Join (ret[node][' DNS ' [' ip4_nameservers ']) asset_info[' serialnumber '] = ret[node][' Serialnu Mber '] asset_info[' virtual '] = ret[node][' virtual '] asset_info[' localhost ' = ret[node][' localhost ' asset_info[ ' mem_total '] = ret[node][' mem_total '] asset_info[' num_cpus '] = ret[node][' Num_cpus '] asset_info[' ip4_interfaces '] = "". Join (ret[node][' ip4_interfaces ' [' eth0 ']) asset_info[' hwaddr_interfaces '] = ret[node][' hwaddr_interfaces ' [' Eth0 '] return asset_infoimport threadingclass MyThread (threading. Thread): Def __init__ (self,func,args= ()): Super (Mythread,self). __init__ () Self.func = Func self.ar GS = args def run (self): Self.result = Self.func (*self.args) def get_resUlt (self): Try:return Self.result # If the child thread does not use the Join method, there may be no Self.result error reported here except Exception: return Noneass =asset.objects.all () ids_list =[i.inner_ip for i in ass]files = Range (len (ids_list)) t_list = []t_da TA = []for i in files:t = MyThread (Auto_asset, (Ids_list[i],)) T_list.append (t) T.start () for T in T_LIST:T.J Oin () # must join, otherwise the mainline Cheng thread runs fast, will not get results t_data.append (T.get_result ()) print (T.get_result ())
