Do Sets exist in Go? (like in Python)
Question: Is there any Go collection similar to 'Set's in python?

alternatives:

  * Is there an easy way of implementing Sets in Go?
  * Is there any method to eliminate duplicates in a slice? 


Answer: You could just have a `map[whatevertype]bool` and set the value to `true`. You
could add every element in a slice as a map key, then use a `range` to get
only the unique ones back out.

    
    
    package main
    import "fmt"
    func main() {
        m := make(map[string]bool)
        s := make([]string, 0)
        s = append(s, "foo")
        s = append(s, "foo")
        s = append(s, "foo")
        s = append(s, "bar")
        s = append(s, "bar")
        for _, r := range s {
            m[r] = true
        }
        s = make([]string, 0)
        for k, _ := range m {
            s = append(s, k)
        }
        fmt.Printf("%v\n", s)
    }
