  1. Dive into
  2. Python

Performance

range() is faster than while loop with i+1 operation.

because int is immutable.

and xrange was faster than range in python2 but in python3 xrange is replaced to range

  • Why is looping over range() in Python faster than using a while loop?

  • Why is there no xrange function in Python3?
