Python multithreading example in detail

Multithreading usually involves opening a new background thread to handle time-consuming operations. It is also very easy for Python to handle background threads. Today, I found an Demo in the official document.

Example code:

import threading, zipfile 
class AsyncZip(threading.Thread): 
  def __init__(self, infile, outfile): 
    self.infile = infile 
    self.outfile = outfile 
  def run(self): 
    f = zipfile.ZipFile(self.outfile, 'w', zipfile.ZIP_DEFLATED) 
    print('Finished background zip of:', self.infile) 
background = AsyncZip('mydata.txt', '') 
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.') 


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 . . .
