Above preferred to next (for readability) using xrange may help speed
depending.

Use xrange i
Which one is better w.r.t. memory allocation but also w.r.t. speed:
## 1.1 ##
def forloop(a,b):
for idx in range(a,b):
## ..
## do something
## ..
## 1.2 ##
def whileloop(a,b):
idx = a
while idx < b:
## ..
