Tooling

I'm in the process of learning Golang, and I'm currently trying to create a Todo project.

My knowledge is limited to the GO base.
Please take a look at my code and tell me how I can delete a task.

The user writes in the console:

add Eat

add Sleep

add Study

Then they write:

list

to check the tasks

For example, if they want to delete the second task (Sleep), and I write del 1, it will delete the first element of the slice, which is 0.

And every time I write del 2, it will still delete the first element.

And now I need to make it so that I can delete:

a) By the title

b) By the number of the task location

I'm stuck at the "Creating a task deletion command" stage. package main

import (
    "bufio"
    "fmt"
    "os"
    "strings"
    "time"
)

type Todo struct {
    Heading      string
    Text         string
    Creationtime time.Time
    Completed    bool
    LeadTime     time.Time
}

func main() {
    todos := []Todo{}
    _ = todos
    scanner := bufio.NewScanner(os.Stdin)

    for {
        scanner.Scan()
        input := scanner.Text()

        words := strings.Split(input, " ")
        switch words[0] {
        case "add":
            todo := Todo{
                Heading:      words[1],
                Text:         strings.Join(words[2:], " "),
                Creationtime: time.Now(),
                Completed:    false,
            }
            todos = append(todos, todo)

        case "list":
            for _, todo := range todos {
                fmt.Println(todo.Heading, todo.Text)
            }
        case "del":
            var n int
            todos = append(todos[:n], todos[n+1:]...)
