Assume all inputs > 0 - Answer: a, b = 0, 1 for r in range(2, int(input())): a, b = b, a + b print(a + b) Raise exceptions for searching a dictionary and output the exception message. Assume the dictionary and a class to create the exception message object are already provided. - Answer: if k in dic: return dic[k] else: raise EntryNotFoundError(f'Value not found for {k}') for k, v in (): if v == value: return k else: raise EntryNotFoundError(f'Key not found for {v}') try: except EntryNotFoundError as excpt: print('<optional message>: ', ge) Replace section of text in my_ - Answer: file_name = 'my_' with open(file_name, 'r+') as f: content = () content = ce('_','_') (0) (content) ate() Sort/clean dictionary - Answer: sorted_dic = {key: dic[key] for key in sorted(dic)} cleaned_dict = {(): () for key, value in my_()}
