在文件中逐行打印项目列表

Question

是否可以逐行打印以下结果？

我试图在print(final \n, file=f)上添加 \n 。 但这行不通。

这是代码：

def calcperm(arr, size):
    result = set([()])
    for dummy_idx in range(size):
        temp = set()
        for dummy_lst in result:
            for dummy_outcome in arr:
                if dummy_outcome not in dummy_lst:
                    new_seq = list(dummy_lst)
                    new_seq.append(dummy_outcome)
                    temp.add(tuple(new_seq))
        result = temp
    return result

lst = [1, 2, 3, 4]
seq = 3
final = calcperm(lst, seq)
print(len(final))
with open('file.txt', 'w') as f:
    print(final, file=f)

Answer 1

用以下代码替换最后两行（ with结构）：

with open('file.txt', 'w') as f:
    for item in final:
        print(item, file=f)

这会将final的所有 24 个元组逐行打印到您的文件中。
