Dotan,
in
>>> barPolicy = GetBarWithPolic(Io)
>>> barPolicy = GetBarWithPolic(File)
what type of object would you imaginge `Io` and `File` to be?
You already exported the functions as `GetBarWithPolicIo` and
`GetBarWithPolicFile` and then you could implement in python
`GetBarWithPolic(str)` and there use something like `return
globals()["GetBarWithPolic%s" % (str,)]()` where you would now do
barPolicy = GetBarWithPolic("Io")
barPolicy = GetBarWithPolic("File")
