Python 多執行緒實例詳解
多執行緒通常是新開一個後台執行緒去處理比較耗時的操作,Python做後台執行緒處理也是很簡單的,今天從官方文件中找到了一個Demo.
實例程式碼:
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.')
結果:
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 . . .
