printing - 将向量折叠为 julia 中的逗号分隔字符串

Question

我有一维值向量。我想将它们转换为一个字符串，其中的值以逗号分隔。 Julia 有没有一种简单的方法来做到这一点？类似崩溃的东西 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}:

使用普通循环打印大部分值，然后打印最后一项(以消除尾随逗号):

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

您还可以使用逗号连接迭代中的每个项目:

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
