# If you need to import additional packages or classes, please import here.def func():# please define the python3 input here. For example: a,b = map(int, input().strip().split())words = input().strip().split(" ")# please finish the function body here.total_words = len(words)new_str = "".join(words)total_length = len(new_str)# please define the python3 output here. For example: print().# print(round(total_length/total_words, 2)) # round有bugprint("%.2f" % (total_length/total_words))if __name__ == "__main__":func()

注意，不要使用round，有bug
