[Tutor] get name of calling class at runtime

[Serdar Tumgoren]

Hi everyone,
I'm trying to create a data-retriever class that executes certain SQL
statements based on the name of a calling class (I'm doing this so I
can group a bunch of SQL statements in one place; they're currently
scattered all over the program and it's getting unwieldy).

Currently, I'm forced to pass in the name of the "caller" from the
calling class:

class DataSources(object):
    def getdata(self, caller):
        if caller == 'CallerA':
          # execute sql for callerA
        elif caller == 'CallerB':
          #execute sql for callerB

class CallerA(object):
    def getdata(self):
        caller = self.__class__.__name__
        dao = DataSources()
        dao.getdata(caller)

class CallerB(object):
    def getdata(self):
        caller = self.__class__.__name__
        dao = DataSources()
        dao.getdata(caller)

So I'm wondering, is there any way to have the DataSources class
access the name of the calling class at runtime, and avoid having to
pass in the "caller" variable? Perhaps there's some other standard
approach to this kind of problem?
