SyntaxError: (unicode error) 'unicodeescape' codec can't decode bytes in position 24-25: truncated \xXX escape

这个错误是由于在Windows系统中的文件路径中使用了反斜杠（\），而在Python字符串中，反斜杠具有转义的作用。这导致了编码错误。要解决这个问题，可以通过以下几种方式：

1. 在字符串前面加上r，表示将字符串作为原始值处理，不进行转义。例如，将路径 'E:\uesless\pi_digits.txt' 改为 r'E:\uesless\pi_digits.txt' ，这样就不会发生编码错误了。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
