def non_empty_lines(text: str) -> int:
    return sum(bool(line.strip()) for line in text.splitlines())


if __name__ == '__main__':
    print("Example:")
    print(non_empty_lines('one simple line\n'))

    # These "asserts" are used for self-checking and not for an auto-testing
    assert non_empty_lines('one simple line\n') == 1
    assert non_empty_lines('') == 0
    assert non_empty_lines('\nonly one line\n            ') == 1
    assert non_empty_lines('''
