# First interhacktionsThe easiest way to make some LEDs blink is using python. There are two ways of executing python code: Using an interactive command line, and saving `.py` files on the card10. The interactive command line is very practical to try out python commands, and debug '.py' files. Directly saving .py files makes the scripts you write available when you have card10 disconnected from your computer.## Using the interactive command line## Saving files to your card10
## Congratulations!When applying your newly learned card10 skills, please have a look at the [general considerations for designing Interhacktions](/en/interhacktions). Also bear in mind that some blinking patterns have been assigned a special meaning for communicating a traveler's [personal state](/ps).
