Do you want to learn how to make different patterns in Python? This article provides 20 Python programs for different pyramid patterns.

2022_08_Pattern-Program-in-Python.jpg

When preparing for Python-related jobs as a beginner, you need to practice pattern programs to better understand conditional statements and loops in Python. Performing pattern printing are interviewer-favorite questions to test your Python skills. This article has compiled a list of the 20 most common pattern programs in python to help you prepare for that job! So, without further ado, let’s get started, shall we?

How to Print Patterns in Python

In Python, we commonly use multiple for loops, and sometimes while loops, too, to print the various patterns. Here, the first outer loop prints the number of rows, and the inner loop prints the number of columns of the pattern. Most pattern programs are variations of each other and work on the same logic.

We will be covering the following pattern programs today:
