SyntaxError: (unicode error) 'unicodeescape' codec can't decode bytes in position 2-3: truncated \UX

SyntaxError: (unicode error) ‘unicodeescape’ codec can’t decode bytes in position 2-3: truncated \UXXXXXXXX escape

最近在学习python，输入如下代码

f=open('C:\Users\Shen Xue\Desktop\read.txt','r')

报错

File "<ipython-input-12-62ddc119b355>", line 1
    f=open('C:\Users\Shen Xue\Desktop\read.txt','r')
          ^
SyntaxError: (unicode error) 'unicodeescape' codec can't decode bytes in position 2-3: truncated \UXXXXXXXX escape

【\U】是八进制的转义符，所以，就会出现以上的错误提醒。utf-8是告诉python interpret如何解释字符串的编码，所以前面写的是utf-8。

修改

f=open(r'C:\Users\Shen Xue\Desktop\read.txt','r')

问题完美解决啦！！！
