Hello, there is something I need to do repeatedly through the for statement It's a little slow, so I found out that the Gui program is a multi-process that runs all at once I don't have a clear example, so I'm asking you a question First code is
def GetResult(self):
self.Loop = threading.Timer(3,self.GetResult) # Retrieves page information every 3 seconds.
for q in range(0,Lastindex+1):
self.getpageinfor(lines[q],self.lineEdit.text())
self.Loop.start()
This code keeps getting page information repeatedly as Lastindex + 1 every 3 seconds. For example,
defGetResult(self):
self.Loop = threading.Timer(3,self.GetResult) # Retrieves page information every 3 seconds.
for q in range(0,10+1):
self.getpageinfor(lines[q],self.lineEdit.text())
self.Loop.start()
It goes like thisAnd every three seconds, you're supposed to get 10 pages of information I get 10 pages in order, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, and what I want is to use a multi-process, so it pops up from 1 to 10 How can I use such a function in a gui program to use multiprocessing?
python
The io operation is not affected by GIL, so you can use multi-thread if you want to get information from the web page.
This is an example of multi-thread based on requests.
import concurrent
import requests
def request_post(url, data):
return requests.post(url, data=data)
with concurrent.futures.ThreadPoolExecutor(max_workers=10) as executor:
res = [executor.submit(request_post, url, data) for data in names]
concurrent.futures.wait(res)
