Python将列表转换为元组和列表的列表元组列表的元组

Question

如何转换列表

    [1, 2, 3, 4, 5]

到元组列表

    [(1, 2, 3, 4, 5)]

和 转换元组

    (1, 2, 3, 4, 5)

到元组列表

    [(1, 2, 3, 4, 5)]

Answer 1

从列表中：

[tuple(x)]

来自元组：

[x]

即

>>> x = [1,2,3]
>>> [tuple(x)]
[(1, 2, 3)]
>>> x = (1, 2, 3)
>>> [x]
[(1, 2, 3)]

Answer 2

arr = [1, 2, 3, 4]
print(arr)
tpl = (arr,)
print(type(tpl), tpl)

输出：

[1, 2, 3, 4]
<class 'tuple'> ([1, 2, 3, 4],)

案例2：

tpl_2 = (1, 2, 3, 4)
print(tpl_2)
arr_2 = [tpl_2]
print(type(arr_2), arr_2)

输出：

(1, 2, 3, 4)
<class 'list'> [(1, 2, 3, 4)]

Answer 3

如何做到以下几点： -

your_list = [1,2,3,4]
new_list = [tuple(your_list)]

在第二种情况下： -

your_tuple = (1,2,3,4)
new_list = [your_tuple]

Answer 4

试试吧！

l=[1, 2, 3, 4, 5]
t=tuple(i for i in l)
t

输出：

(1, 2, 3, 4, 5)

和

tl = [t]
tl

输出：

[(1, 2, 3, 4, 5)]
