Go / golang - does it have equivalent of python "pip install" to install packages?

Question

Have just started learning about Go (do people say "Go" or "Golang"?)

I got the hello world example running. I have my GOROOT AND GOPATH set up.

Now I want to do something bit more advanced, for example open csv file, for which I found a tutorial to do that here

In order to make this script work, I need the packages that are being imported eg "bufio", "encoding/csv", etc.

Do I have to manually search https://github.com/golang/go/wiki/Projects or some other repository, download and unzip these into my GOPATH "pkg" directory?

Or does Go/Golang have something equivalent to Python's "pip install" that would do this for me?

import (
    "bufio"
    "encoding/csv"
    "os"
    "fmt"
    "io"
)

func main() {
    // Load a TXT file.
    f, _ := os.Open("C:\\Users\\bb\\Documents\\Dropbox\\Data\\bc hydro tweets\\bchtweets.csv")

    // Create a new reader.
    r := csv.NewReader(bufio.NewReader(f))
    for {
    record, err := r.Read()
    // Stop at EOF.
    if err == io.EOF {
        break
    }
    // Display record.
    // ... Display record length.
    // ... Display all individual elements of the slice.
    fmt.Println(record)
    fmt.Println(len(record))
    for value := range record {
        fmt.Printf("  %v\n", record[value])
    }
    }
}

Go has go get which is similar to pip install in Python. (ref)

UPDATE: Starting in Go 1.17, installing executables with go get is deprecated. go install may be used instead.(ref)

Read every single line of this beautiful documentation's section: https://golang.org/doc/code.html#Organization

BTW, all packages you have in your import section are from standard library. So you don't have to install anything for this example.

Best way to install a package is go get which simply clones a git repo to your $GOPATH/src and you should stick to it as long as you can. If you must use some package version you can create fork for a specified commit and go get that fork or use one of many vendoring toolds https://github.com/golang/go/wiki/PackageManagementTools
