[英]How do I define a slice of slices containing an int and a slice of strings in Go?
It would look something like this: 它看起来像这样:
[[1,["a", "b", "c"]], [2,["z", "x", "y"]]]
Intuitively I would do something like [][]int[]string, but that's not valid: syntax error: unexpected [, expecting semicolon or newline or }
, so how would I do it? 凭直觉我会做类似[] [] int [] string的操作,但这是无效的:
syntax error: unexpected [, expecting semicolon or newline or }
,那么我该怎么做?
Slice of T: var x []T
T切片:
var x []T
Slice of slice of T: var x [][]T
T的切片:
var x [][]T
Slice of T1 and T2: You need to put T1 and T2 into a struct. T1和T2的片段:您需要将T1和T2放入一个结构中。
So for: slice of (slices containing { int and a slice of strings } ). 因此,适用于:切片(包含{int和字符串切片}的切片)。 It would usually be something like:
通常是这样的:
type foo struct {
i int
s []string
}
var x [][]foo
But your example looks more like just a []foo
: 但是您的示例看起来更像是
[]foo
:
bar := []foo{
{1, []string{"a", "b", "c"}},
{2, []string{"z", "x", "y"}},
}
fmt.Println("bar:", bar)
// bar: [{1 [a b c]} {2 [z x y]}]
