Hello everyone, welcome back to programminginpython.com! I recently started a new series on pattern programming, I explained how to print a Floyd’s Triangle pattern in the previous post. Here I will explain to you how to print a pyramid pattern or a triangle pattern in Python.
You can also watch the video on YouTube here.
Pyramid Pattern – Code Visualization
Task
Python Program to print a Pyramid/Triangle Pattern.
Approach
- Read an input integer for asking the range of the triangle using
input() - Run 3 for loops, one main for column looping and other 2 sub-loops for row looping, in the first loop, loop through the range of the triangle for column looping.
- In the second loop, loop through the value of the range – 1, this is to print space
- In the third loop, loop through the value of i+1 and print

__author__ = 'Avinash' # Print a Triangle # Range of the triangle num = int(input("Enter the range: \t ")) # i loop for range(height) of the triangle # first j loop for printing space ' ' # second j loop for printing stars '*' for i in range(num): for j in range((num - i) - 1): print(end=" ") for j in range(i + 1): print("*", end=" ") print() |
Output
That is it for this tutorial. Also feel free to look at programs on other patterns or some algorithms implementation in python here or look at all of the posts here.
