python - 多次附加用户输入

Question

我想将用户输入存储在列表中，根据程序随后做出决定的长度。

就目前而言，用户输入在每次用户提供输入时存储多次，但它应该只附加一次。

moves = int(input("Enter the number of moves: "))

throw00 = []
throw01 = []
throw10 = []
throw11 = []

player_move_dif = [] #create an empty list out of your for-loop

for i, turn in enumerate(range(moves)): #use enumerate() to count the loops
    if i >= 0: #first move has no previous one
        player_move_dif.append(input("Choose your move number %s (0 or 1):" % (turn+1)))
        player_move_2 = int(player_move_dif[i])
        player_previous_move = int(player_move_dif[i-1])
    else:
        player_move_dif.append(input("Choose your move number %s (0 or 1):" % (turn+1)))
        player_move_2 = int(player_move_dif[i])
        player_previous_move = int(player_move_dif[i-1])
        #continue
       
    for turn in range(moves): #store player moves in the respective lists    
        if player_move_2 == 0 and player_previous_move == 0:
            throw00.append(player_move_2)
        elif player_move_2 == 0 and player_previous_move == 1:
            throw01.append(player_move_2)
        elif player_move_2 == 1 and player_previous_move == 0:
            throw10.append(player_move_2)
        else:
            throw11.append(player_move_2)

因此，经过 5 圈后，列表（此处throw11）的大小为 25 而不是 5。

我试过extend而不是，append但这给了我一个 TypeError 。

这将起作用，因为这是错误

moves = int(input("Enter the number of moves: "))

throw00 = []
throw01 = []
throw10 = []
throw11 = []

player_move_dif = [] #create an empty list out of your for-loop

for i, turn in enumerate(range(moves)): #use enumerate() to count the loops
    if i >= 0: #first move has no previous one
        player_move_dif.append(input("Choose your move number %s (0 or 1):" % (turn+1)))
        player_move_2 = int(player_move_dif[i])
        player_previous_move = int(player_move_dif[i-1])
    else:
        player_move_dif.append(input("Choose your move number %s (0 or 1):" % (turn+1)))
        player_move_2 = int(player_move_dif[i])
        player_previous_move = int(player_move_dif[i-1])
        #continue
