Square pattern in Python

I'd be happy to help you with that! Here's a simple script in Python to generate a square pattern:

import turtle

def draw_square(t, size):


for _ in range(4):


t.forward(size)


t.right(90)


window = turtle.Screen()


window.bgcolor("white")


my_turtle = turtle.Turtle()


my_turtle.shape("turtle")


my_turtle.color("blue", "green")


for _ in range(5):  # Draw 5 squares


draw_square(my_turtle, 50)  # Size of the square


my_turtle.penup()           # Lift the pen


my_turtle.forward(60)       # Move to next position


my_turtle.pendown()          # Drop the pen


window.mainloop()

Let me explain what this script does:

Import turtle module which is used for creating simple graphics in Python. Define a function draw_square(t, size) that uses turtle graphics to draw a square of given size. Create a turtle object and set its shape, color, and background color. Use the draw_square() function to draw 5 squares of different sizes (in this case, all of them are 50 units in size). Move the turtle to next position after drawing each square. The script then enters a loop until it draws all the squares. Finally, it runs the main event loop (window.mainloop()) for turtle graphics.

So when you run this script, you'll see 5 blue and green squares drawn in your screen!

How to print right angled triangle in Python using while loop?

I'm happy to help you with that!

Printing a right-angled triangle in Python can be achieved by utilizing a while loop. The idea is to keep track of the number of rows and columns, and adjust the spacing accordingly.

Here's an example code snippet:

rows = 5  # You can change this value to print a different-sized triangle

i = 1  # Initialize the row counter


while i <= rows:


print(' ' * (rows - i), end='')  # Print leading spaces


j = 1  # Initialize the column counter


while j <= i:


print('*', end=' ')  # Print asterisks


j += 1


print()  # Move to a new line


i += 1

Let's break down what this code does:

We set rows to a desired value (e.g., 5). This will determine the height of the triangle. The outer while loop iterates from 1 to rows. In each iteration, we print leading spaces using ' ' * (rows - i). For each row, we have an inner while loop that prints asterisks (*) up to a maximum number of columns equal to the current row value (i). After printing the asterisks, we move to a new line with print().

Here's the output for the code above:

    *

You can adjust the rows value to create different-sized triangles. For example, if you set rows = 3, the output will be:

  *

I hope this helps you understand how to print a right-angled triangle in Python using a while loop!
