How do I find the type of an object in Go? In Python, I just use typeof
to fetch the type of object. Similarly in Go, is there a way to implement the same ?
Here is the container from which I am iterating:
for e := dlist.Front(); e != nil; e = e.Next() {
lines := e.Value
fmt.Printf(reflect.TypeOf(lines))
}
I am not able to get the type of the object lines in this case which is an array of strings.
The Go reflection package has methods for inspecting the type of variables.
The following snippet will print out the reflection type of a string, integer and float.
package main
import (
"fmt"
"reflect"
)
func main() {
tst := "string"
tst2 := 10
tst3 := 1.2
fmt.Println(reflect.TypeOf(tst))
fmt.Println(reflect.TypeOf(tst2))
fmt.Println(reflect.TypeOf(tst3))
}
Output:
string
int
float64
