改进版本.

from collections import Counterimport rewith open("models.py",encoding="utf-8") as f:    txt = f.read()c = re.split("\W",txt)Cnt =Counter(c)#1. 获取到的是一个大字典里面统计了单词出现的次数.print(Cnt)ret = Cnt.most_common(10)#2. 统计了前十个单词出现的次数.print(ret)  lt =[]for i in ret:    x= i[0]    lt.append(x)    #3. 统计了前十个单词出现的次数放在了一个列表里面.print(lt)

打印结果：
