新人求指导，请问这个python代码为什么运行不了。
···f = open('C:/Users/Administrator/Desktop/yingwen.txt',"r")
all_words = []
for s in f.readlines():
s = s.replace(","," ").replace("."," ").lower()
all_words.extend(s.split(" "))
all_words = list(set(all_words))
all_words.sort()
f2 = open('C:\Users\Administrator\Desktop\ying.txt','w')
f2.write("\n".join(all_words))
f2.close()
···
主要实现的功能是讲一本英文小说的文章全部采集成单次罗列到一个新的txt文章里。但是怎么运行都是错误。错误内容是：
