Change the title above to describe your issue and add your feedback here, including code if necessary
package main
should be:

import (
"fmt"
"math"
)

func main() {
fmt.Println(math.Pi)
}

Yes, that is the point of the exercise. To see the error when you run it with the lower case version and then see the correct running when changed to upper case.

To fix the error, rename math.pi to math.Pi and try it again.
