在Julia中将向量折叠为逗号分隔的字符串

Question

我有一维向量值。我想将它们转换为带有逗号分隔值的字符串。朱莉娅有一个简单的方法可以做到这一点吗？像崩溃一样r

{julia}
julia> x = [24,122,63,24,83,56,54,175,11,11,24,51,85,92,74,500,80,127,126,59,111,155,132,202,64,164,1301]

#I want output like this as a string
#24,122,63,24,83,56,54,175,11,11,24,51,85,92,74,500,80,127,126,59,111,155,132,202,64,164,1301,27

#I have tried something like this
[julia> [print(i,",") for i in x]
24,122,63,24,83,56,54,175,11,11,24,51,85,92,74,500,80,127,126,59,111,155,132,202,64,164,1301,27-element Array{Void,1}:

Answer 1

使用普通循环打印大多数值，然后打印最后一项（以消除结尾的逗号）：

julia> for i in @view x[1:end-1]
           print(i, ',')
       end; print(x[end])
24,122,63,24,83,56,54,175,11,11,24,51,85,92,74,500,80,127,126,59,111,155,132,202,64,164,1301

您还可以使用逗号将Iterable中的每个项目连接起来：

julia> print(join(x, ','))
24,122,63,24,83,56,54,175,11,11,24,51,85,92,74,500,80,127,126,59,111,155,132,202,64,164,1301
