问题 I'm working on this code (on python) that reads a text file. The text file contains information to construct a certain geometry, and it is separated by sections by using keywords, for example, the file: *VERTICES 1 0 0 0 2 10 0 0 3 10 10 0 4 0 10 0 *EDGES 1 1 2 2 1 4 3 2 3 4 3 4 contains the information of a square with vertices at (0,0), (0,10), (10,0), (10,10).
