遇到的报错python篇

1python的转译问题

正确代码如下：

s = 'Hello world \n 文本文件的读取方法\n文本文件的写入方法\n'

with open(r'C:\Users\ShiYa\Desktop\11.txt','w') as fp:
    fp.write(s)
with open(r'C:\Users\ShiYa\Desktop\11.txt') as fp:
    print(fp.read())
    
    

问题代码：

s = 'Hello world \n 文本文件的读取方法\n文本文件的写入方法\n'

with open('C:\Users\ShiYa\Desktop\11.txt','w') as fp:
    fp.write(s)
with open('C:\Users\ShiYa\Desktop\11.txt') as fp:
    print(fp.read())
    
    

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

这次只需要在路径前加  r  就可以了。
