An infinite loop that never ends; it never breaks out of the loop.

This can be done with break keyword. This loop is obviously an infinite loop because the logical expression on the while statement is simply the logical constant True: n = 10 while True: print (n, end=' ') n = n - 1 print ('Done!') In this loop, the condition itself is True, so the computer will always continue running the loop. 2: Learn Python Basics with CodeCraft. With great power comes great responsibility.
