How to create, load and save files in Mu
You need to understand what each of the following three buttons do:
New, Load and Save buttons
- New - Click on this button to create a new empty file. Before you can run
your code you’ll need to save it (i.e. give it a filename).
- Load - When you click this button a file selector dialog box pops up and
you should click on the Python file you’d like to load into Mu (or press
cancel).
- Save - Clicking this button saves the file in the currently selected tab.
If the file was newly created then Mu will ask you for a name for the file.
Copy/Rename Files
If you want to create a newly named copy of the current file you
can rename it by clicking on the filename in the file's tab in Mu.
Don't Use Python Module Names
It's tempting to name your new file that uses the turtle
module as "turtle.py". Don't do this! If you name
your file after a module you're using in your code
then Python will break because it's trying to import
your code rather than the code from Python's standard
library!
