Adding random numbers to a variable

I'm looking for an output like this

Computer Choice: 5
Total: 5
Continue? Yes or No
Computer Choice:2
Total: 7

It adds up the random numbers every time it's created. This is the part I'm trying to get to work:

 if player_bet <= Player.total_money_amount:

    import random
    computer_choice = random.randint(1, 5) # Creates random number
    computer_total =+ computer_choice # Does not work. Also used += same result
    print('Computer choice: ', computer_choice)
                print('Total: ', computer_total)

      player_yes_or_no = input('Continue? Yes or No')
      if player_yes_or_no == 'Yes':
      pass

Current output

Computer Choice: 5
Total: 5
Continue? Yes or No
Computer Choice: 2
Total: 2 

As you can see it does not add up the random int that where created. If I do += it gives an error

Edit: I get the same output when I do

 computer_total = 0
 computer_total += computer_choice
