we have added underscores in numerical constants for the better readability of the code. This feature has been introduced in Python 3.6. If you want to use PyRandLib version 1.2 or above with Python 3.5 or below, removing these underscores should be sufficient to have the library running correc...
Think for example how we package Python modules in Fedora. The summary and description is basically repeated with an additional statement on which version of Python it targets based on the flavor. In my view, implementing this feature would make things like proper multilibbing automatic, as well...
