Answer 1

Simplest and clearest, if you want your code "in line":

theimage = td[0].a.img
if theimage is not None:
   use(theimage['src'])

Or, preferably, wrap the None check in a tiny function of your own, e.g.:

def getsrc(image):
  return None if image is None else image['src']

and use getsrc(td[0].a.img).

Starting from tr:

for td in tr.findChildren('td'):
    img = td.findChild('img')
    if img:
        src = img.get('src', '')  # return a blank string if there's no src attribute
        if src:
            # do something with src
