splatting an array inside a string

Starting from and array of numbers such as

a = [1,2,3]

I need to get the following string

"values in (1,2,3)"

If I try a simple interpolation 

"values in (#{a})"  => "values in ([1,2,3])"

I could use gsub to remove [ and ] but I'd rather find a cleaner way. Any suggestions?

Thanks

An alternative:

a, bracs = [1,2,3], %w{[] ()}

p "values in #{a}".tr(*bracs) #=> "values in (1, 2, 3)"

Try this:

"values in (#{a.join(",")})"

Here is one more :

a = [1,2,3]
p "values in (#{a* ","})" # => "values in (1,2,3)"
