python，如何把嵌套列表写入txt

现在有一个这样的嵌套列表[[2, 1, 4, 3], [3, 2, 1, 4], [4, 3, 2, 1], [1, 4, 3, 2]]，

尝试写入一个txt文档：

2  1  4  3
3  2  1  4
4  3  2  1
1  4  3  2

PS;考虑在不使用模块的情况下

list1 = [[2, 1, 4, 3], [3, 2, 1, 4], [4, 3, 2, 1], [1, 4, 3, 2]]
with open('try.txt', 'a') as f:
    for i in list1:
        for j in i:
            f.write(str(j)+' ')
        f.write('\n')

data = [[2, 1, 4, 3], [3, 2, 1, 4], [4, 3, 2, 1], [1, 4, 3, 2]]
with open('ddd.txt','w',encoding='utf-8') as f:
    for item in data:
        temp = ' '.join(map(lambda x:str(x),item))
        f.write(temp+'\n')
