Example 1: python async await

import urllib.request as urllib2
async def getPic():
pic = Image.open(urllib2.urlopen("https://c.files.bbci.co.uk/E9DF/production/_96317895_gettyimages-164067218.jpg"))
return pic
async def main_def():
print("A")
print("Must await before get pic0...")
pic0 = await asyncio.gather(getPic())
