How to alternate between players?

Question

I have to make a card game in which the starting player changes after each round or mini round (up to me to decide) but I have no clue how to alternate between the 2 players. After reading online, I tried using the cycle function from itertools but that creates further problems...

The problem is that I do not know how to alternate between the 2 players without messing up the rest of the program (displaying the player's hand and the scoring system)

To clarify in advance, the code snippets I am about to provide work perfectly as long as I do not alternate between the starting players.

Code:

print("Player 1, your cards are: ", hands[0])
print("Player 2, your cards are: ", hands[1])

In this case I want the hands index to change accordingly to the Player if i use the cycle function.

if cards.bigger_card(hands[0][play_1 - 1], hands[1][play_2 - 1], trump[0][1]) == 0:
    print("Congrats Player 2! You won this mini round.")
    score["score_2"] += 1
else:
    print("Congrats Player 1! You won this mini round.")
    score["score_1"] += 1

Here the score should update according to the Player that won the round.

I'm not sure if I've understood your question well enough. But I'll try.

To simply alternate between two index i.e. 0, 1, you can add a variable to store current turn and alternating it like this:

currentTurn = 0
def switchTurn():
  return (currentTurn + 1) % 2

Usage:

print(currentTurn)
# output: 0

switchTurn()
print(currentTurn)
# output: 1

print(hands[currentTurn])
# output player 2nd's hands (or cards)
