codePost snippet to programmatically reassign students/partnerships on already-uploaded submissions

# get the API key here: https://codepost.io/settings

# mapping a codePost ID to students
# (note that this could be loaded from a CSV file)

codepost.configure_api_key(API_KEY)

    # the property "students", we need to cast it to the same
    # dynamic list data type as the list we are replacing (this
    # is a bug of the SDK that will be fixed in an upcoming
    # version)
