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:
importthreading,zipfile classAsyncZip(threading.Thread): def__init__(self,infile,outfile): threading.Thread.__init__(self) self.infile=infile self.outfile=outfile defrun(self): f=zipfile.ZipFile(self.outfile,'w',zipfile.ZIP_DEFLATED) f.write(self.infile) f.close() print('Finishedbackgroundzipof:',self.infile) background=AsyncZip('mydata.txt','myarchive.zip') background.start() print('Themainprogramcontinuestoruninforeground.') background.join()#Waitforthebackgroundtasktofinish print('Mainprogramwaiteduntilbackgroundwasdone.')
结果:
Themainprogramcontinuestoruninforeground. Finishedbackgroundzipof:mydata.txt Mainprogramwaiteduntilbackgroundwasdone. Pressanykeytocontinue...
