So the file format is like this?:

"""point(1., 3., 3.9893824234)
point(2., 2., 3.9893824234)
point(7.2, 2.12, 3.9893824234)
point(5.31, 2.32, 3.9893824234)"""

How do you know how many sides each polygon has?


You can read a file like this:

f = open("E111B.s","r")
lines = f.readlines()

# if the last line does not have a newline at the end,
#  add one.
if lines[-1][-1] != "\n":
  lines[-1] += "\n"

points = []

for line in lines:
  # get rid of the "point(" and ")\n"
  point = line[len("point("):-2]

  # convert the parts into floats
  points.append( map(float, point.split(",")) )
  

For drawing we need to know how many points make up a
polygon.


Good luck!
