A simple countdown exe using python is implemented for your reference as follows
Use tkinter to create an interface to implement the countdown function.
- Use (1) to implement a seconds countdown.
- Using threads to avoid interface jams
- Detecting the global flag bit in the thread's loop ensures that the timed thread resets and exits.
- Use pyinstaller -F -w to generate an exe file, -w to hide the console, -F to generate a single file
The code is as follows:
#!/usr/bin/python3.8
