这道题需要将给出的text里面的单词根据单词长短分类，并按字母顺序排列

def words(text):
    text=text.replace(',','').replace('\\','').replace('?','').replace('.','').replace("’",'').replace(':','').replace(';','')
    words_seperate=text.split()
    new_list=set()
    max_count=0
    for i in words_seperate:
        new_list.add(i.lower())
        if len(i)>max_count:
            max_count=len(i)
　　　　　　　　#max_count=max(max_count,len(a))
    dic_matching={}
    for number in range(1,max_count+1):
        same_len=[]
        for i in new_list:
            if len(i)==number:
                same_len.append(i)
        order_same=sorted(same_len)
        dic_matching[number]=order_same
    for key,value in dic_matching.items():
        if value:
            print('Words of length {}:'.format(key))
            print('  ',value)





a=words('You must not fall into the common error of mistaking these simpletons ’\ ’for liars and hypocrites. They believe honestly and sincerely that their ’\ ’diabolical inspiration is divine. Therefore you must be on your guard against ’\ ’your natural compassion. You are all, I hope, merciful men: how else could you ’\ ’have devoted your lives to the service of our gentle Savior? You are going ’\ ’to see before you a young girl, pious and chaste; for I must tell you, gentlemen, ’\ ’that the things said of her by our English friends are supported by no evidence, ’\ ’whilst there is abundant testimony that her excesses have been excesses of religion ’\ ’and charity and not of worldliness and wantonness.')

这里创捷一个新的set时用s=set(),添加新元素时用add
