How do i get aspect ratio of system display resolution in python?
When I check for display resolution in Ubuntu, I see 1024x768(4:3). How do I get aspect ratio 4:3 in Python?

What do you mean "check for display resolution"? Are you using some API to get the resolution now?John Zwinck– John Zwinck2013-07-04 10:49:31 +00:00Commented Jul 4, 2013 at 10:49

I meant display resolution we find in system display settings. The resolution I see is 1366x768(16:9). I have been able to get the resolution part...But I do not know if its possible to get the aspect ratio using Python.user2550098– user25500982013-07-04 12:12:20 +00:00Commented Jul 4, 2013 at 12:12

For this answer I used the following resource: How to get the screen size in Tkinter?
The question you're asking is (1) How do I get the screen resolution in Python (2) How do I convert this resolution to a aspect ration. I solved this problem in the following way:
import Tkinter
import Fraction as f
root = Tkinter.Tk()
width = root.winfo_screenwidth()
height = root.winfo_screenheight()
frac = f.Fraction(width,height)
print frac
Note that this gives the lowest denominator. So for a 1680x1050 screen this is 8/5 instead of a possibly expected 16/10.

Thanks for your reply Peter. I do not see the use of Fraction here..I just want the ratio specified in the system..for ex..my system has a resolution of 1366x768 with aspect ratio 16:9...How do i get 16:9 in Python.
Peter Smit
1366x768 does not work like you expected because it is not exactly 16:9. It only approximates 16:9.

OK...but is it possible to get that ratio in Python.
Peter Smit
If you are only interested in a few aspect ratios and want to include approximate values you could just try to compare the fraction in decimals: 1.33 for 4:3, 1.6 for 16:10, 1.77 for 16:9. Replace frac = float(width)/float(height) to get the fraction in decimals.
