is there a possibility generate a variable in python which equals to the

Not easily (although I have long been considering adding support for
that, but haven't ever got close to an actual implementation)
The makepy utility generates the following code:
def WriteFlagValue(self, ByteIndex=defaultNamedNotOptArg,
BitIndex=defaultNamedNotOptArg, pData=defaultNamedNotOptArg):
"""Writes single bit, byte, word, or double word to the Control Engine
Flag memory."""
return self._oleobj_.InvokeTypes(27, LCID, 1, (24, 0), ((3, 1), (3, 1),
(16396, 1)),ByteIndex
, BitIndex, pData)
The parameter where the variant type is checked is "pData".
The type definition should be:
(16396, 1) # 16396 = 0x400C -> 0x4000 = VT_BYREF, 0x000C=12 = VT_VARIANT
I'm not sure what you mean by "should be" - it *is* that, right?
You should be able to change that definition (or just clone it) to
VT_BYREF|VT_I2 - the object will still be called with a variant and the
type will be VT_BYREF|VT_I2 - which IIUC is what you want.
(This is what I meant above by "not easily" - an easier way would be to
introduce a new object called "Variant" and add special support in the
type-handling code for this object - but that is what I referred to as
nowhere near an implementation)
