Python 多线程实例详解

多线程通常是新开一个后台线程去处理比较耗时的操作，Python做后台线程处理也是很简单的，今天从官方文档中找到了一个Demo.

实例代码：

import threading, zipfile 
 
class AsyncZip(threading.Thread): 
 def __init__(self, infile, outfile): 
 threading.Thread.__init__(self) 
 self.infile = infile 
 self.outfile = outfile 
 def run(self): 
 f = zipfile.ZipFile(self.outfile, 'w', zipfile.ZIP_DEFLATED) 
 f.write(self.infile) 
 f.close() 
 print('Finished background zip of:', self.infile) 
 
background = AsyncZip('mydata.txt', 'myarchive.zip') 
background.start() 
print('The main program continues to run in foreground.') 
 
background.join() # Wait for the background task to finish 
print('Main program waited until background was done.') 

结果:

The main program continues to run in foreground. 
Finished background zip of: mydata.txt 
Main program waited until background was done. 
Press any key to continue . . .
