Python function to map random user ID's (e.g., crowdsource platform) to a unique Prodigy session name

def generate_random_userids(num_ids):
    passwords = []
    for _ in range(num_ids):
        password = ''.join(random.choices(string.ascii_letters + string.digits, k=12))
        passwords.append(password)

def assign_session_id(new_user_id, session_ids):
    # assumes session_ids are in order, hence next would be 1 more than length
    next_session_number = len(session_ids) + 1
    next_session_id = "user" + str(next_session_number)
    return {new_user_id: next_session_id}

## Test example
# new_user_id = "gxG1SyMBJb6I"

# assigned_sessions = [
#     {"aASB1k10tYmA": "user1"},
#     {"6rSei5t0sb8f": "user2"},
#     {"GiFTnff72opR": "user3"},
#     {"gzFuSyEuIJwh": "user4"}
# ]

# result = assign_session_id(new_user_id, assigned_sessions)
# print(result)
# {"gxG1SyMBJb6I": "user5"}

# General example

user_ids = generate_random_userids(10)

assigned_sessions = []
for new_user_id in user_ids:
    result = assign_session_id(new_user_id, assigned_sessions)
    assigned_sessions.append(result)
    for key,val in result.items():
        print(f"For user {key}, send them to https://my-prodigy-url.com?session={val}".format(key,val))

# For user aASB1k10tYmA, send them to https://my-prodigy-url.com?session=user1
# For user 6rSei5t0sb8f, send them to https://my-prodigy-url.com?session=user2
# For user GiFTnff72opR, send them to https://my-prodigy-url.com?session=user3
# For user gzFuSyEuIJwh, send them to https://my-prodigy-url.com?session=user4
# For user gxG1SyMBJb6I, send them to https://my-prodigy-url.com?session=user5
# For user wHV0a8xbqskh, send them to https://my-prodigy-url.com?session=user6
# For user TgNjgNBr0wxt, send them to https://my-prodigy-url.com?session=user7
# For user EL7nHI9nMY5b, send them to https://my-prodigy-url.com?session=user8
# For user mrCMIbRqwGTJ, send them to https://my-prodigy-url.com?session=user9
# For user AvZqcq7WsOaH, send them to https://my-prodigy-url.com?session=user10
