I want to write function that prints a value of a variable, for
debugging. Like:
with
myVariable = "parrot"
otherVariable = "dead"
probe(myVariable)
probe(otherVariable)
instead of the longer
print "myVariable = ", myVariable
print "otherVariable = ", otherVariable
Is that even possible?
The function would look like
def probe(var):
nameOfVar = someMagic(var)
print nameOfVar, " = ", var
but can someMagic(var) find the variable name? Is that possible?
That question really doesn't quite make sense. Consider all the
ways such a function can be called:
someMagic(42)
someMagic(40+2)
someMagic(f(123))
someMagic(*argTuple)
someMagic(**kwDict)
someMagic(array[42])
None of which have a variable name associated with the argument.
Yet, the answer to your question is not quite absolutely "no". Python
has lots of introspection capabilities, including, perhaps, getting at
and parsing the original code to find the call. But there's nothing
direct for what you want.
