How to Check if String contains only Alphabets in Go - Step by Step Examples

How to Check if String contains only Alphabets in Go ?

Answer

To check if a string contains only alphabets in Go, you can use a loop to iterate through each character in the string and check if it is an alphabet using Unicode values.

✐ Examples

1 Check if String contains only Alphabets using loop and Unicode values

In this example,

We create a variable named str1 with a value of "HelloWorld".
We iterate through each character in the string and check if its Unicode value falls within the range of alphabets.
If all characters are alphabets, we set containsOnlyAlphabets to true, otherwise false.
Finally, we print the result to the console.

Go Program

package main
import (
	"fmt"
	"unicode"
)
func main() {
	str1 := "HelloWorld"
	containsOnlyAlphabets := true
	for _, char := range str1 {
		if !unicode.IsLetter(char) {
			containsOnlyAlphabets = false
			break
		}
	}
	fmt.Println("String contains only alphabets:", containsOnlyAlphabets)
}

Output

String contains only alphabets: true

2 Check if String contains only Alphabets using loop and Unicode values (with non-alphabet characters)

In this example,

We create a variable named str2 with a value of "Hello123".
We iterate through each character in the string and check if its Unicode value falls within the range of alphabets.
If all characters are alphabets, we set containsOnlyAlphabets to true, otherwise false.
Finally, we print the result to the console.

Go Program

package main
import (
	"fmt"
	"unicode"
)
func main() {
	str2 := "Hello123"
	containsOnlyAlphabets := true
	for _, char := range str2 {
		if !unicode.IsLetter(char) {
			containsOnlyAlphabets = false
			break
		}
	}
	fmt.Println("String contains only alphabets:", containsOnlyAlphabets)
}

Output

String contains only alphabets: false
