Not that it changes your reply, but just for my own sanity:
int('7' * 10 ** 6) <- does this not just type-cast a char into an int?

Meaning that rather then consuming 1024k as you stated, it would consume
2048k at the peak of the calculation(2bytes per char? * 1m = 2048k) then
typecasting to int would drop it back down to 1k (1byte per int * 1m = 1024k

So, just for sake of getting to a point since I missed the one by the
original poster.. why would you not convert that 7 from a char to an int
first? That calculation is almost instant, and it doesn't require the memory
rollercoaster that this calculation would require..

Anyways.. back to the poster...

Perhaps you wanted an error like this?

print '=' * 1000000000
Traceback (most recent call last):
  File "<input>", line 1, in ?
MemoryError
