How to determine whether a file exists in golang

The way Golang determines whether a file or folder exists is to use the error value returned by the os.Stat() function to determine:

If the error returned is nil, it shows that the file or folder exists (Recommended learning: Go )

## This If the wrong type returned uses OS.ISNOTEXIST () If it is judged to be true, it means that the file or folder does not exist

If the error returned is of other types, it is not sure whether it exists

func PathExists(path string) (bool, error) {
	_, err := os.Stat(path)
	if err == nil {
		return true, nil
	}
	if os.IsNotExist(err) {
		return false, nil
	}
	return false, err
}
