In most debiggers(including Pythons) you can still do that
with a boolean condition provided the condition does not
itself contain a function call. Simply evaluate the condition
in the debugger - eg using the print command.
But if the condition has a function in it this is not wise
since the function may have side-effects so every time you
call it may result in a different result.
So my advise is to ony use the
trick on side-effect free simple expressions, otherwise
go with the more verbose options.
Same applies to the C ?: operator or the python shortcuts
using 'and' and 'or'...
