Question

I tried it on here but it can not print the long numbers like this

for i in range(1,222222222222222):
    print i

Error:

Traceback (most recent call last):
  File "x.py", line 1, in <module>
    for i in range(1,222222222222222):
MemoryError

Answer 1

Use xrange instead of range.
range generates a list, stores it in the memory and performs the loop on each item. This generates memory errors when dealing with quite big numbers.

xrange is a generator not a list, items are created on the fly, so it does not harm for the memory

I hope this helps
