Question

Find an example of a Python program on the Web that illustrates the program’s decisions using if and while statements. Provide a link for the source.

What is happening in your programming example? Describe it in English as an algorithm.

After the else statement executes, which program statement executes next in your example?

Answer 1

""" A simple program to demonstrate WHILE LOOP, IF ELSE condition """ # initialize n = 5 n = 5 # if we don't know how many times loop runs then use while loop # WHILE LOOP checks whether n > 0 # if yes then it decrements n by 1 and prints n # After it uses a if statement to check whether n == 2 # if yes then it breaks the WHILE LOOP # else It print "Loop done" after printing each value of n while n > 0: n -= 1 print(n) if n == 2: break else: print("Loop done.")

STEPS

1) Asign n = 5

2) The program uses a WHILE LOOP to check whether n > 0.

3) If n > 0 it decrements n by 1 and prints n

4)After that it uses a if statement to check whether n is equal to 2

5)If n == 2 is True then it breaks the while loop else it prints "Loop done" after each value of n

After the ELSE statement it again starts the condition in WHILE  LOOP
