Hello World (Python programming)¶

This use case example shows you how to create and run a simple Python script.

Create a new, empty Python file¶

1. Create a new Celbridge project (or use an existing one).

2. Right-mouse click in the file explorer and choose to add a new Python file named hello_world.py:

3. choose menu: File | New File

4. enter the file name as hello_world.py
5. choose type: Python Script (.py)

Edit the Python file¶

1. The new Python script file should be created and appear in the file explorer panel.

2. Edit your new script, by double clicking on file hello_world.py in the file explorer panel:

   • the file should open in the code editor in the Documents panel

3. Type the following simple Python print statement:

print("Hello, Wworld!")

Note

There is no need to click anything to save your edits - since Celbridge automatically saves your changes as you type

Create/Open a Python console document¶

If you started this project as a Python project, you'll already have a python.console Python console document in your project.

If you don't have a Python console document:

1. Create a new Console document named python.console

   • choose menu: File | New File
   • enter the file name as python.console
   • choose type: Console (.console)

   

2. Open the Console document & ensure its Console Type is Python

   • open the console settings
   • select Python from the Console Type dropdown menu

   

Run the Python file¶

1. Run your Python script.

   • A simple way to do this is by right-mouse clicking in the file explorer over file hello_world.py, and choose the Run option.

2. In the Python console document you should see the CLI comment %run "hello_world.py" followed by the text "Hello, World!" printed out on the next line.

Congratulations - you've created and executed a Python script using Celbridge!
