Answer 1

I'm not comfortable with Django, so I show a couple of option in plain Python, given the collections:

something1 = [1,2,3,4]
something2 = [1,2,3,4,5,6,7,8,9,10]

You can access objects by index (not the same as database index):

i = 1
for e1 in something1:
  print(e1)
  i += 1

for i2 in range(i,len(something2)):
  print(something2[i2])

Or slice the last collection:

for e1 in something1:
  print(e1)

for e2 in something2[len(something1):-1]:
  print(e2)

Of course, the last collection has to be the longest.
