# islower
|

|
## Instructions
|
||
|
|
|
||
|
|
Write a function that returns `true` if the `string` passed in parameter only contains lowercase characters, and that returns `false` otherwise.
|
||
|
|
|
||
|
|
## Expected function
|
||
|
|
|
||
|
|
```go
|
||
|
|
func IsLower(str string) bool {
|
||
|
|
|
||
|
|
}
|
||
|
|
```
|
||
|
|
|
||
|
|
## Usage
|
||
|
|
|
||
|
|
Here is a possible [program](TODO-LINK) to test your function :
|
||
|
|
|
||
|
|
```go
|
||
|
|
package main
|
||
|
|
|
||
|
|
import (
|
||
|
|
"fmt"
|
||
|
|
piscine ".."
|
||
|
|
)
|
||
|
|
|
||
|
|
func main() {
|
||
|
|
fmt.Println(piscine.IsLower("hello"))
|
||
|
|
fmt.Println(piscine.IsLower("hello!"))
|
||
|
|
|
||
|
|
}
|
||
|
|
```
|
||
|
|
|
||
|
|
And its output :
|
||
|
|
|
||
|
|
```console
|
||
|
|
student@ubuntu:~/piscine/test$ go build
|
||
|
|
student@ubuntu:~/piscine/test$ ./test
|
||
|
|
true
|
||
|
|
false
|
||
|
|
student@ubuntu:~/piscine/test$
|
||
|
|
```
