Hello!

Say I had a single group of six players, and six unique roles(_ROLE) in the constants section. Is there a way to reassign these roles randomly each round? 

Best and Thank You

If, as you say, there is a SINGLE group of n people in the session, with n unique roles, just shuffle session players in each round:

def creating_session(subsession):
    subsession.group_randomly()

Im still very new to oTree, where should this code be placed to shuffle players once they start the game. 

Again, thank you for the advice.

For instance, look at the sample matching pennies code here: https://github.com/oTree-org/oTree/blob/lite/matching_pennies/__init__.py
There are many other examples in the github repo.
