Python Multithreading Tutorial #1 - What is a Thread?

This python multithreading tutorial talks about what a thread is and how it compares to a process. Multithreading is a commonly used strategy to improve the efficiency of code. When multiple threads are running if the current thread delays or is waiting for something then the next thread will start executing.

PLEASE DO MORE PYTHON PROBLEMS AND SOLUTIONS!!
Like one a week?

this video helped me reduce lag in my applications that have over 250, 000 objects

nice video man, i was unable to understand at beginning when i looked at the code, but then i understood evrything after your illustrations.

If it's possible to show msec in the clock time this may be a better demonstration to show how the threads wait and start.

Awesome tutorial dude! You're really talented :))

Is there any priority? Lets say thread 1 sleeps so thread 2 starts and takes 5 minutes without a break to finish. thread 1 (half executed) would then have to wait 5 minutes until it resumes and finishes then?

"Multithreading" is a very big word when it comes to plain python. You won't be getting any significant performance gain from doing it.


The problem is that Python's GIL will protest against any form of parallelisation. I tried to build a package that could deliver a Python based BSP package, but was unable to get the GIL to play nice in any generalised case. Hence, the project is currently on the backburner.

My main wonder is what happens if you set two threads to delay for the same intervals of time

where did you learn this, can u share the resource, if it is a pdf?

[devpatel]

Perfect explanation .. keep it up 👻👍👍👌

I'm just getting into threading for my kivy app. The reason being is that I have an nslookup function bound to a kivy button and on the button press a progress spinner should appear while the nslookup is running. However when I press the button the app freezes (presumably because the function is an nslookup and doesn't actually interact with the GUI). So my thinking is that I run the function and the progress spinner animation on different threads so the spinner doesn't have to wait for the nslookup to complete. Am I thinking along the right lines here? Will threading help me to achieve this or should I be looking into something else?

I am looking into making a device manager that would interact with several comports (at least 2-3, but could be as many as 6) that would read logs/write commands. What would be the most efficient implementation? Running each port in its own thread? Perhaps dedicate a core to running all of the serial port threads? How would I share the logs read into each serial port with the main thread running the computation/testing?

[maulikmadhavi]

why different number of empty spaces? Can anyone explain? Thanks

[aryanbhatia]

When are deep learning tutorials coming ??

[kitgary]

Any thought about the gevent? Is it good?

[ashishsrivastava]

Please make video on vscode..its very good.. but lot of issue we face while running e.g. extension do not load, update json files etc ( Python ML developer )

[manishkumar-bhcc]

Bro can you upload a tutorial in webscraping in python

[chujuntang]

I think it's Python which cannot run two threads at the same time due to GIL.

OMG PYGAMES WEBSITE IS DOWN WHATS HAPPENING?!?!?!?!?
