This flow shows how you write, save, and run Python code on a Raspberry Pi, then see the output in the terminal.

Execution Sample

Raspberry Pi

print('Hello from Raspberry Pi!')

This code prints a greeting message to the terminal on the Raspberry Pi.

Execution Table

Step	Action	Code Executed	Output	State
1	Start program	print('Hello from Raspberry Pi!')		Program ready to run
2	Execute print statement	print('Hello from Raspberry Pi!')	Hello from Raspberry Pi!	Message printed
3	Program ends	No more code		Program finished

💡 Program ends after printing the message

Key Moments - 2 Insights

Why do I need to open the terminal to run Python code on Raspberry Pi?

You run Python code in the terminal because it lets the Raspberry Pi execute your saved script and show the output, as shown in step 4 of the execution_table.

What happens if I forget to save my Python file before running it?

If you don't save the file, the terminal can't find your code to run it, so no output appears. Saving is essential before running, as the flow shows.

Visual Quiz - 3 Questions

Look at the execution_table, what is the output at Step 2?

A Error message

B No output

C Hello from Raspberry Pi!

D Program finished

💡 Hint

Check the Output column at Step 2 in the execution_table

At which step does the program finish running?

A Step 1

B Step 3

C Step 2

D After Step 3

💡 Hint

Look at the State column in the execution_table for when the program ends

If you change the print message, how does the execution_table change?

A Output at Step 2 changes to the new message

B Step 1 action changes

C Program ends earlier

D No change in output

💡 Hint

The Output column at Step 2 shows the printed message, so changing the message changes this output

Full Transcript

This visual shows how to run Python code on a Raspberry Pi. First, you write your Python code and save it as a file. Then, you open the Terminal on the Raspberry Pi and run the code using the command 'python3 filename.py'. The Python interpreter reads and executes your code, printing any output to the Terminal. Finally, the program ends after running all commands. This simple flow helps beginners understand how to see their Python programs work on the Raspberry Pi.
