Python Program To Print Pascal’s Triangle (2 Ways) by Amit Rawat · June 17, 2019 In this program, we will learn how to print Pascal’s Triangle using the Python programming language. This is a good thing, but it needs one minor change to make the Pascal's Triangle generator work in Python 2: replace the range(n) with xrange(n). Although the algorithm is very simple, the iterative approach to constructing Pascal's triangle can be classified as dynamic programming because we construct each row based on the previous row. The outer for loop situates the blanks required for the creation of a row in the triangle and the inner for loop specifies the values that are to be printed to create a Pascal’s triangle. This is less like the for keyword in other programming languages, and works more like an iterator method as found in other object-orientated programming languages. To print the inverted Pascal's triangle we will use three loops. The Pascal's triangle is as given below: 1. else, for loop and while loop concept in detail.
