The following is corrected:

import screeninfo
import re
import sys


"""
GetScreenInfo()

cross platform creates a dictionary with an entry for each monitor
tied to users computer. the key is constructed as follows:
   monitor{n} n is sequentiallty assigned beginning with 1

Usage: GetScreenInfo(win_scale=.6, offset_scale=.1)
   where: scale is % of full screen, so default .6 = 60 % and
          offset is % of scaled width & height

each entry contains a nested dictionary with four values:
   swidth = scaled_width
   sheight = scaled height
   hoffset = horizontal offset
   voffset = vertical offset4

example: 
>>> from GetScreenInfo import GetScreenInfo
>>> gsi = GetScreenInfo(win_scale=.8, offset_scale=.2)
>>> print(gsi.monitor_info)
>>> {'monitor1': {'swidth': 1920, 'sheight': 1080, 'hoffset': 384, 'voffset': 216}}
   {'monitor1': {'swidth': 1920, 'sheight': 1080, 'hoffset': 384, 'voffset': 216}}

Tested on Windows 7 with python 3.6
Needs testing on Linux and Apple

This is exactly what I get:

it appears that prnt.sc isnt working with img tags?


but yet imgur works

not sure? Although you could always upload the image as an attachment which shows it in post.

Know you were asking for Linux and Mac, but I have Windows on right now

Output:
Windows 10; Python 3.6; Single LCD Monitor

mon: [monitor(1920x1080+0+0)]
{'monitor1': {'swidth': 1536, 'sheight': 864, 'hoffset': 384, 'voffset': 216}}

##########  Switched screen size

Thanks all.
I think it's working ok now.
