1、打开JetBrains PyCharm软件。
3、本代码的注释如下：sentence=input("请输入需要统计的英文句子:")#将文本中涉及的标点用空格替代for ch in ",.?!": sentence=sentence.replace(ch," ")#利用字典统计词频words=sentence.split()dicts={}for word in words: if word in dicts: dicts[word]+=1 else: dicts[word] = 1#对统计结果排序items=list(dicts.items())#对单词出现的次数reverse=True降序items.sort(key=lambda x:x[1],reverse=True)for item in items: word,count=item print("{:<12}{:>5}".format(word,count))
