Read-only attribute in module

[Mateusz Loskot]

Hi,

I'm implementing Python 3 extension using the Python C API.
I am familiar with defining new types, implementing get/set for attributes, etc.

I'm wondering, is there any mean to implement attribute in module
scope which is read-only?

So, the following

import xyz
print(xyz.flag)  # OK
xyz.flag = 0    # error due to no write access

Best regards,
