I was charming when i saw your solution, but after 5 minutes and some changes <pre class='brush: python'>def completely_empty(val): return check(val) def check(val,flag=True): try: for i in val: if flag: flag=completely_empty(i) return flag except Exception as e: return False </pre> and <pre class='brush: python'>def completely_empty(val, flag=True): try: for i in val: if flag: flag=completely_empty(i) else: break return flag except TypeError: return False </pre> and one more <pre class='brush: python'>def completely_empty(val, flag=True): try: return all(completely_empty(i) for i in val if flag) except TypeError: return False </pre> came to a just recursion-solution like most people <pre class='brush: python'>def completely_empty(val): try: return all(map(completely_empty, val)) except TypeError: return False </pre>
