The difference between xrange and range in Python

These two are basically used at the time of the cycle.

 for  in range (0, xrange (0,Print 

The results of both outputs are the same, in fact there are many differences, and range generates a list object directly:

A = Range (0,100printprint  a #[0,1,2 ...] Print

Xrange does not generate a list directly, but instead returns one of the values in each call

A = xrange (0,100print  type (a) #<type ' xrange ' >
Print a  #xrange (100)
Print

So the performance of Xrange cycle is better than range, especially when the return is very large!
