First case:

class FileDict:
    def __init__(self):
        self.files = {}
    def AddFile(self, key, filename)
        self.files[key] = filename
    def GetFile(self, key):
        try:
            fp = open(self.files[key], 'r')
        except KeyError:
            print "Error!  No such file registered!"
            return None
        text = fp.read()
        fp.close()
        return text

Of course, you might want to add some code to verify that the filename you're
being fed exists, is a valid (fully qualified) path, etc, etc...

Second case:

def test1():
    print "Testing!"
def test2():
    print "But I don't like spam!"

FuncDict = { "first" : test1, "second" : test2 }

>>> FuncDict['first']()
Testing!
>>> FuncDict['second']()
But I don't like spam!
