The condition is evaluated, and if the condition is true, the code within the block is executed. Print i as long as i is less than 6: i = 1 while i 6: print(i) i += 1. Iterables. The way we do it here is using the indexes and getting the item with the index each time. It acts round the route during the execution of entire program and monitors the approaching and execution of occasions. While all the ways provide similar basic functionality, they differ in their syntax and condition checking time. # Prints out the numbers 0,1,2,3,4 for x in range(5): print(x) # Prints out 3,4,5 for x in range(3, 6): print(x) # Prints out 3,5,7 for x in range(3, 8, 2): print(x) "while" loops. Generally, for-loops fall into one of the following categories: And here is the new typing exercise for this chapter: onetoten = range (1, 11) for count in onetoten: print (count) It handles nested loops better than the other examples.
