如果我有一组数字：

com.google.android.youtube.player W/MediaPlayer: info/warning (3, 0)
com.google.android.youtube.player W/YouTubeAndroidPlayerAPI: (unknown) Warning: unexpected playback play 0 surpressed

并打印出来，我得到

a = [1,2,3]

但如果我有一个数组，比如说，元组：

[1,2,3]

当我打印它时，我得到：

b = [(1,2),(3,)]

如何避免打印类型？

Answer 1

无法抑制。

julia> b = [(1,2), (3,)]
2-element Array{Tuple{Int64,Vararg{Int64}},1}:
 (1,2)
 (3,)

可能正在打印类型以向您显示您包含Vararg类型。

如果您想要没有消息的输出，可以继续为Base.show

编写包装器

如何在朱莉娅打印类型？
