如何从列表中删除值并在同一索引处将其更改为另一个值？

Question

我想更新板子以添加玩家输入并删除 position 索引处的值并添加一个新值：

def place_marker(board, marker, position): 
    # Anything false than being in acceptable_values
    index_position = 'Wrong'
    #Keep Asking while the input not in acceptable_values
    while index_position not in ["1",'2','3','4','5','6','7','8',"9"]:     
        index_position = input('Choose a number from 1 to 9: ')     
        if index_position not in ["1",'2','3','4','5','6','7','8',"9"]:
            print('Invalid Input')
        
    position = int(index_position) 
    board.pop(position)

Answer 1

要在同一位置更改列表的值，您只需要通过它的索引来引用它，如下所示：

my_list = [1,2,3,4,5]

my_list[3] = 100   # reference the 4th item (list starts at 0 index)

print(my_list)

返回：

[1, 2, 3, 100, 5]
