Syntaxerror was just reported when running the python file: ‘Unicode error)’ Unicode scape ‘codec can’t decode bytes in position 2-3: tr. in fact, the reason for this error is the escape problem.
Cause analysis: in the windows system, the file path can be read by \, but in the Python string \, there is an escape meaning,
For example, \ t can represent tab and \ n represents line feed, so we need to take some measures to make \ not be interpreted as escape characters. There are currently 3 solutions
1. Add r before the path to keep the original value of the character.
2. Replace with double backslash
3. Replace with forward slash
