Yes, although it is not clear *what* it is that you are missing.
Here is my guess: you fail to see that

You have two calls to reTest and so reTest needs to return twice. One
return is from the reTest(True) call back to reTest(False). The second
return is from reTest(False) back to the prompt.
What were you expecting to happen?

Don't do that. Do this instead:
result =
the final returned value is: []
the two values printed is (note i only have one print statement
printing "print result",. however, in the actualality, it's printed
twice):
printing result:
['should be the only thing returned']
printing result:
[]
therefore, sadly, i don't thinkg you've understand

hi, i have the following recursive function (simplified to demonstrate
the problem):
>>> def reTest(bool):
... result = []
... if not bool:
... reTest(True)
... else:
... print "YAHHH"
... result = ["should be the only thing returned"]
... print
