windows issues

from PIL import Image
img = Image.open("alice.png")

# This won't work
img.show()

# This will work
from IPython.display import display
display(img)

# corrected in readme 
14:07: if you have windows instead of source venv/bin/activate it will be .\venv\Scripts\activate.bat

Errata: 
33:53 I forgot a `return` in the last line of `handle_user_input`. 
It should be `return handle_user_input(user_input)` not `handle_user_input(user_input)` 

40:00 `ls | grep "coin.pngcoin"` won't work on Windows. 
Do this instead: 

import os 
def file_exists(filename): 
  return os.path.isfile(filename) 
file_exists("bobs.pngcoin")

After installing and running WSL and Xming ( https://sourceforge.net/projects/xming/ )
the magic command to be added to WSL was: `export DISPLAY=127.0.0.1:0.0`
