Errors in Pytch projects

If there is an error in your Python program, this will be shown in the ‘Errors’ tab of the information pane. The error report includes clickable buttons to take you to the point in your code which caused the problem.

TODO: Fill in structure of below.

• This is one big difference from Scratch, where your program never crashes.

• How best to explain the concept of build (maybe “launch” is a better word?) and runtime errors will need some thought.

• Your program can have problems at launch time, which means Pytch can’t even start running your project.

• Or can have problems at run time, which are problems which only show up once your project is running. Perhaps there is a problem which only shows up when one of your Sprites is clicked.

• When an error happens, Pytch stops your project completely so you can investigate.

• The problem is reported in the Errors tab of the info panel. Occasionally more than one error might happen at the same time; then they’re all reported at once.

• Each error report explains what’s happened, and gives you clickable buttons to take you to the places in your code causing the problem.

Debugging

TODO: Suggestions about how to investigate when things go wrong.

Some errors are confusing; explain them here; e.g., tuple not callable if you forget comma between one detailed Costume spec and the next.
