The front part and back part is about the file, how to extract only the middle x, y data to carry on the drawing, and other data not read?

With the open (path) as f:
Data=(https://bbs.csdn.net/topics/f.readlines)
Data=https://bbs.csdn.net/topics/data [then]
For I in data:
I=i. trip ()
Print (I)
Can look like this

If the content of each file content is different, can consider to use regular expressions to match your data!

However, what data you are x which is y?
