Threads not running in parallel for a system command

This is my script It appears that both starts are executed immediately. However, the sounds are not played in parallel but one after the other. When running the following shell script both sounds play at the same time. What makes Python run the commands sequentially instead of parallel? I’m using Big Sur with with the standard Python (2.7).

Python Tkinter variable not updating in other thread

So I have a python script which accesses a website every minute, reads the page, and pings me if a certain data was placed on the website in that minute. I’m expanding this script to have a menu and a way to switch between different data points. The GUI and the script work well independently. However, the variable current_event_id does

Start and Stop threads with while loop

I’m building a tkinter GUI to retrieve incoming data from a device (through request) and appending them into a csv file, while having a preview of these data. I use thread but struggle to understand it properly, especially how to pause and restart it. When I click on the start button, my threads are working properly. Once I try to

threading.Thread.start() method execution time depends on the Thread target method

I am wondering why threading.Thread().start() method execution time is dependent on the Thread’s target method. I assumed that start() method just signalizes system that Thread can execute and does not do any processing. To illustrate this behavior: Results: Why threads start time differs for pass_target_function and calculate_target_function? Edit: Based on Steve’s answer individual thread start time is measured. Result match

asyncio: Wait for event from other thread

I’m designing an application in Python which should access a machine to perform some (lengthy) tasks. The asyncio module seems to be a good choice for everything that is network-related, but now I need to access the serial port for one specific component. I’ve implemented kind of an abstraction layer for the actual serial port stuff, but can’t figure out

What is the use of join() in threading?

I was studying the python threading and came across join(). The author told that if thread is in daemon mode then i need to use join() so that thread can finish itself before main thread terminates. but I have also seen him using t.join() even though t was not daemon example code is this i don’t know what is use
