一个文件里有一段文本：

初学python，想把其中的unicode字符转化为中文，开始想直接用encode('utf-8').decode('utf-8')的方法转换，结果却没有任何变化，搞不明白，以为反斜杠的问题，想把多余的反斜杠去掉，结果用replace去除反斜杠的时候真把人搞晕了，网上也看了一些解释，但用起来仍很糊涂，请大神指点迷津！

4.py

1. with open("4.txt", "r", encoding="unicode-escape") as f:
   
2.    a = f.read()
   
3. 
   
4. print(a.encode('UTF-8').decode('unicode-escape'))

问题好像是字符串中\\表示单反斜杠，\是特殊字符，无法直接把\\替换为\。反正因为反斜杠出现一些在菜鸟如我看来奇奇怪怪的问题。
看来得找另外的方法，呼唤大神！

先谢过大神！然后再学习。

你看看行不行，以上是在 windows 上运行, 如果是 linux ,  putty 也應該能正常显示

十分感谢！我也是windows,结果正常。原来是\\u9b54之类是unicode-escape编码，受教了！
