Answer 1

What is the result that you're after?
['ab', 'ac', 'ad', 'ae', ...] ???
if so then
print([''.join(e) for e in y])

This is the same as;

l = []
for e in y:
l.append(''.join(e))

print(l)

Answer 2

for elems in y:
x = "".join(elems)
y.append(x)

This creates an infinite loop. You're increasing the length of y with each iteration.

Answer 3

ChaoticDawg, what do you suggest? Doing if len(y) == 0 is also doing nothing.
