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 . . . 感谢阅读,希望能帮助到大家,谢谢大家对本站的支持!
