字符串列表-golang

Question

I'm trying to make a list of Strings in golang. I'm looking up the package container/list but I don't know how to put in a string. I tried several times, but 0 result.

Should I use another thing instead of lists? Thanks in advance.

Answer 1

If you take a look at the source code to the package you linked, it seems that the List type holds a list of Elements. Looking at Element you'll see that it has one exported field called Value which is an interface{} type, meaning it could be literally anything: string, int, float64, io.Reader, etc.

To answer your second question, you'll see that List has a method called Remove(e *Element). You can use it like this:

fmt.Println(l.Len()) // prints: 4

// Iterate through list and print its contents.
for e := l.Front(); e != nil; e = e.Next() {
    if e.Value == "4" {
        l.Remove(e) // remove "4"
    } else {
        fmt.Println(e.Value)
    }
}

fmt.Println(l.Len()) // prints: 3

By and large, Golang documentation is usually pretty solid, so you should always check there first.
