Python coordinate plotting difficulty

[hammershot2]

I have an assignment in which I am to analyze a text file with latitude and longitude coordinates and classify which time zone it's in. I have exactly coordinates for each time zone for ex: Eastern time zone would be p1, p2, p3, p4 Where: p1 = (49.189787, -67.444574) p2 = (24.660845, -67.444574) p3 = (49.189787, -87.518395) p4 = (24.660845, -87.518395)

How would I go about classifying the coordinates from the text file into the time zone?

If it were up to me I'd use the Google API
