Two ways to open a process in Python

1. How to open a process

 fromMultiprocessingImportProcessImport TimedefWork (name):#Define a function    Print('task <%s> is runing'%name) Time.sleep (1)    Print('task <%s> is AAAAA'%name)if __name__=='__main__': P1=process (target=work,args= ('Yxwang',))#produces a process object, followed by the name of the function to be executed. Here, args and a tupleP2=process (target=work,kwargs={'name':'User01'})#You can also use the Kwargs and dictionary method. P1.start ()#execution. is equal to running a child process under the current program. P2.start ()Print('QQQQQQQQQQ')

Execution Result:

2. The second way to open a process

 fromMultiprocessingImportProcessImport TimeclassMyprocess (Process):#inherit the Process class    def __init__(Self,name): Super ().__init__()#invokes a method in the parent class. Self.name=namedefRun (self):#there must be a way to run.        Print('task <%s> is runing'%self.name) Time.sleep (1)        Print('task <%s> is AAAAA'%self.name)if __name__=='__main__': P=myprocess ('Egon')#get an objectP.start ()#Run    Print('TTTTTT')
