Module 5 Lab Activity: Iterative Programming Deliverables

Module 5 Lab Activity Iterative Programmingdeliverables Pyth

Write Python programs to solve the following problems, including appropriate comments for your name, date, and program purpose. Test each program thoroughly and debug as needed.

Problem 1 – Print "Hello World" 100 times

Create a flowchart illustrating the execution flow (using draw.io), then write the Python code to print "Hello World" 100 times with a loop.

Solution:

# Your name
The date
This program prints "Hello World" 100 times
for i in range(100):
print("Hello World")

Problem 2 – List of Numbers Operations

Given the list of numbers: [12, 10, 32, 3, 66, 17, 42, 99, 20]

1. Write a loop to print each number on a new line.
2. Write a loop to print each number and its square on a new line.

Solution:

# Your name
The date
This program processes a specific list of numbers
numbers = [12, 10, 32, 3, 66, 17, 42, 99, 20]
Print each number
for num in numbers:
print(num)
Print each number and its square
for num in numbers:
print(f"{num} squared is {num**2}")

Problem 3 – Draw a Filled Regular Polygon

Ask the user for the number of sides, length of each side, line color, and fill color. Then draw and fill the regular polygon accordingly.

Solution:

# Your name
The date
Draws a regular polygon based on user input
import turtle
Get user inputs
sides = int(input("Enter the number of sides: "))
length = float(input("Enter the length of each side: "))
line_color = input("Enter the color of the line: ")
fill_color = input("Enter the fill color: ")
Set up the turtle
t = turtle.Turtle()
t.color(line_color)
t.fillcolor(fill_color)
Draw and fill the polygon
t.begin_fill()
angle = 360 / sides
for _ in range(sides):
t.forward(length)
t.left(angle)
t.end_fill()
turtle.done()

Problem 4 – Multiples of Three and Five

Create a flowchart of the logic (using draw.io), then write a program to iterate integers 1 through 50, printing specific messages for multiples of 3, 5, or both.

Solution:

# Your name
The date
This program prints special messages based on divisibility from 1 to 50
for num in range(1, 51):
if num % 15 == 0:
print("Divisible by both")
elif num % 3 == 0:
print("Divisible by three")
elif num % 5 == 0:
print("Divisible by five")
else:
print(num)

Problem 5 – Draw a Creative Picture with Turtle

Use turtle graphics to draw a creative picture, experimenting with turtle methods such as moving, turning, changing colors, and drawing shapes.

Solution:

# Your name
The date
Drawing a colorful spiral pattern with turtle
import turtle
import random
Set up turtle
t = turtle.Turtle()
t.speed(0)
turtle.colormode(255)
Draw a colorful spiral
for i in range(360):
r = random.randint(0,255)
g = random.randint(0,255)
b = random.randint(0,255)
t.pencolor(r, g, b)
t.forward(i * 3 / 4 + i)
t.left(59)
turtle.done()
