How to Run a Python Script on Boot with a Raspberry Pi?

Estimated read time 2 min read

To run a Python script on boot with a Raspberry Pi, you can add a command to the /etc/rc.local file, which is executed during the boot process. Here’s a step-by-step guide:

Step 1: Open a terminal on your Raspberry Pi.

Step 2: Open the /etc/rc.local file for editing using a text editor, such as nano, with root privileges:

sudo nano /etc/rc.local

Step 3: Add the command to run your Python script before the exit 0 line in the /etc/rc.local file. For example, if your Python script is located at /home/pi/myscript.py, the command to run it would be:

python3 /home/pi/myscript.py &

The & at the end of the command is used to run the script in the background, so that the boot process is not delayed.

Step 4: Save the changes and exit the text editor.

Step 5: Reboot your Raspberry Pi to execute the /etc/rc.local file and run your Python script on boot:

sudo reboot

After rebooting, your Python script should be automatically executed during the boot process.

Note: Make sure your Python script has executable permissions. You can set the permissions using the chmod command, for example:

chmod +x /home/pi/myscript.py

This allows the script to be executed as a standalone program.
