_thread implementation process

• In Python programs, threads can be used in two ways: using functions or using classes to wrap thread objects. When using the thread module to process threads, you can call the function start_new_thread () to generate a new thread.

• 1 _thread.start_new_thread ( function, args[, kwargs] )

   

• Where function is a thread function; args represents the parameter passed to the thread function, he must be a tuple type; kwargs is an optional parameter.

• 1  import _thread
   2  import time
   3  def fun1 ():
   4      print ( ' start running fun1 ' )
   5      time.sleep (4 )
   6      print ( ' run fun1 end ' )
   7  def fun2 ():
   8      print ( ' start running fun2 ' )
   9      time.sleep (2 )
   10      print ( ' End of run fun2 ' )
   11  if  __name__ ==' __Main__ ' :
   12      Print ( ' runs ' )
   13      # to create a thread 
  14      _thread.start_new_thread (fun1, ())
   15      _thread.start_new_thread (fun2, ())
   16      the time.sleep (7)

  1  start running
   2  start running fun1
   3  start running fun2
   4  run fun2 end
   5 run fun1 end
