如何将列表中的每一项包装到相应的列表中

# 原始一维列表
one_dimensional_list = [1, 2, 3, 4, 5, 6]

# 定义每行的元素个数
row_size = 2

# 将一维列表转换为二维列表
two_dimensional_list = [one_dimensional_list[i:i + row_size] for i in range(0, len(one_dimensional_list), row_size)]

print(two_dimensional_list)

[[1, 2], [3, 4], [5, 6]]

# 填充默认值
default_value = 0
two_dimensional_list = [one_dimensional_list[i:i + row_size] + [default_value] * (row_size - len(one_dimensional_list[i:i + row_size])) for i in range(0, len(one_dimensional_list), row_size)]

# 动态计算每行的元素个数
row_size = len(one_dimensional_list) // 3  # 假设分成3行
two_dimensional_list = [one_dimensional_list[i:i + row_size] for i in range(0, len(one_dimensional_list), row_size)]
