This post is part of a new series I'm starting where I quickly outline small Python snippets.
|
|
|
|
|
|
|
|
|
|
If you have an application that you want to gracefully exit when the user presses CTRL-C here's the short snippet
|
|
|
|
|
```python
|
|
|
|
|
import signal
|
|
|
|
|
import sys
|
|
|
|
|
|
|
|
|
|
# Function that gets called when interrupt is found
|
|
|
|
|
def signal_handler(sig, frame):
|
|
|
|
|
print('You pressed Ctrl+C!')
|
|
|
|
|
sys.exit(0)
|
|
|
|
|
|
|
|
|
|
# Attach the function to the interrupt signal
|
|
|
|
|
signal.signal(signal.SIGINT,signal_handler)
|
|
|
|
|
|
|
|
|
|
print('Press Ctrl+C')
|
|
|
|
|
```
|
