[FIXED] Visual Studio Code - Python debugging - Step into the code of external functions when executing

Issue

In a Python project, how do you tell the built-in VSCode debugger to step into the code of functions from other libraries on execution?

I know it is possible for functions implemented in standard libraries by adding a

"debugOptions": ["DebugStdLib"]

to your configuration in launch.json as specified here, however it does not seem to be possible to force the debugger to step into the code of non-standard modules, such as the ones you have written yourself and imported into the current file.

Solution

In order to improve the accepted answer by John Smith, it is worth mentioning that now the option has been renamed again. The new option is

"justMyCode": false

and as per the documentation

When omitted or set to True (the default), restricts debugging to user-written code only. Set to False to also enable debugging of standard library functions.
