如何用字符列表填充2D矩阵？

def fill_matrix_with_char_list(char_list, rows, cols):
    matrix = [[''] * cols for _ in range(rows)]
    char_list_len = len(char_list)
    for i in range(rows):
        for j in range(cols):
            matrix[i][j] = char_list[(i * cols + j) % char_list_len]
    return matrix

# 示例用法
char_list = ['A', 'B', 'C', 'D', 'E', 'F']
rows = 3
cols = 4
matrix = fill_matrix_with_char_list(char_list, rows, cols)
print(matrix)

[['A', 'B', 'C', 'D'],
 ['E', 'F', 'A', 'B'],
 ['C', 'D', 'E', 'F']]
