To print a variable’s sort, you should utilize the %T verb within the fmt.Printf() operate format. It’s the only and most beneficial manner of printing sort of a variable.
bundle important
import (
"fmt"
)
func important() {
t1 := "textual content"
t2 := []string{"apple", "strawberry", "blueberry"}
t3 := map[string]float64{"strawberry": 3.2, "blueberry": 1.2}
t4 := 2
t5 := 4.5
t6 := true
fmt.Printf("t1: %Tn", t1)
fmt.Printf("t2: %Tn", t2)
fmt.Printf("t3: %Tn", t3)
fmt.Printf("t4: %Tn", t4)
fmt.Printf("t5: %Tn", t5)
fmt.Printf("t6: %Tn", t6)
}
Alternatively, you should utilize the TypeOf() operate from the reflection bundle replicate. Nonetheless, it makes use of advanced and costly runtime reflection, so when you simply have to print the kind of a variable, it’s higher to make use of the primary technique.
bundle important
import (
"fmt"
"replicate"
)
func important() {
t1 := "textual content"
t2 := []string{"apple", "strawberry", "blueberry"}
t3 := map[string]float64{"strawberry": 3.2, "blueberry": 1.2}
t4 := 2
t5 := 4.5
t6 := true
fmt.Printf("t1: %sn", replicate.TypeOf(t1))
fmt.Printf("t2: %sn", replicate.TypeOf(t2))
fmt.Printf("t3: %sn", replicate.TypeOf(t3))
fmt.Printf("t4: %sn", replicate.TypeOf(t4))
fmt.Printf("t5: %sn", replicate.TypeOf(t5))
fmt.Printf("t6: %sn", replicate.TypeOf(t6))
}
Each strategies return the identical output:
t1: string
t2: []string
t3: map[string]float64
t4: int
t5: float64
t6: bool
