A interesting fact is that for loop is a bit faster compared to while loop in python. Because in for loop range/xrange is used which is implemented in C(in python's library) whereas in while loop we make use of some incremental statement specifically at the end of sentence like (i+=1) which is interpreted. Thus for loop is faster than while loop. Reference:
