# star_out Return a version of the given string, where for every star (*) in the string the star and the chars immediately to its left and right are gone. So "ab*cd" yields "ad" and "ab**cd" also yields "ad". ``` star_out("ab*cd") -> "ad" star_out("ab**cd") -> "ad" star_out("sm*eilly") -> "silly" ``` This exercise was taken from [codingbat.com](https://codingbat.com/prob/p139564) and has been adapted for the Python language. There are many great programming exercises there, but the majority are created for Java. ## Starter Code ```python def star_out(string: str) -> str: pass result = star_out('ab*cd') print(result) ``` ## Tests ```python from main import star_out def test_star_out_1(): assert star_out('ab*cd') == 'ad' def test_star_out_2(): assert star_out('ab**cd') == 'ad' def test_star_out_3(): assert star_out('sm*eilly') == 'silly' def test_star_out_4(): assert star_out('sm*eil*ly') == 'siy' def test_star_out_5(): assert star_out('sm**eil*ly') == 'siy' def test_star_out_6(): assert star_out('sm***eil*ly') == 'siy' def test_star_out_7(): assert star_out('stringy*') == 'string' def test_star_out_8(): assert star_out('*stringy') == 'tringy' def test_star_out_9(): assert star_out('*str*in*gy') == 'ty' def test_star_out_10(): assert star_out('abc') == 'abc' def test_star_out_11(): assert star_out('a*bc') == 'c' def test_star_out_12(): assert star_out('ab') == 'ab' def test_star_out_13(): assert star_out('a*b') == '' def test_star_out_14(): assert star_out('a') == 'a' def test_star_out_15(): assert star_out('a*') == '' def test_star_out_16(): assert star_out('*a') == '' def test_star_out_17(): assert star_out('*') == '' def test_star_out_18(): assert star_out('') == '' ```
