将列表转换为元组序列

Question

Is there anyway to convert

A = [((0,0,0),), ((1,1,1),), ((2,2,2),) ]

to this

B = ((0,0,0),), ((1,1,1),), ((2,2,2),)

In other words, all I want to do is remove the end brackets so that I can input B into a certain argument. I do not want any outer parentheses/brackets/quotations on B

Any help would be appreciated. Thanks

Answer 1

If you are passing A as an argument to a function fn(A1, A2, A3) , you can pass the elements of A individually as follows:

fn( *A )

The * operation on a list/tuple when passed to a function unpacks the elements in the list/tuple.

Answer 2

假设你想要一个字符串表示：

B = ", ".join(repr(t) for t in A)

Answer 3

A quick and dirty way to do it would be to do something like this:

B = A[0], A[1], A[2]

Which results in

(((0, 0, 0),), ((1, 1, 1),), ((2, 2, 2),))
