Example of concurrent and sequential running of Python thread

CopyCode The Code is as follows: #-*-coding: UTF-8 -*-
Import threading
Import time
Def fun (name, ls_name, front_thread = none ):
'''''
Thread start Function
Use front_thread to run threads in an orderly manner
'''
Time. Clock ()
Time. Sleep (2)
# If front_thread exists, the current thread will be run only after the front_thread is completed
If front_thread! = None:
Front_thread.join ()
Ls_name.append (name)
Print "thread % s: % s" % (name, time. Clock ())

If _ name _ = '_ main __':
Ls_result_name = []
Ls_thread = []
Time. Clock ()
# Start Up 1000 threads one by one
For I in range (0, 10 ):
If Len (ls_thread) = 0:
T = threading. Thread (target = fun, argS = (I, ls_result_name, none ))
Else:
T = threading. Thread (target = fun, argS = (I, ls_result_name, ls_thread [-1])
T. Start ()
Ls_thread.append (t)

# Wait until all threads end
For T in ls_thread:
T. Join ()

Print 'ls _ result_name: ', ls_result_name
Print "main thread: % s" % time. Clock ()

running result:
