How to write a pascals triangle in python using lists. Meilleure réponse. 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. 5 points each. 20 points - The following calls all work as intended: pascals_triangle(1), pascals_triangle(2), pascals_triangle(3) and pascals_triangle(4). For a given integer , print the first rows of Pascal's Triangle. In Pascal’s Triangle, the value of a cell is the sum of its two shoulders. 1 Solution. In a Pascal's Triangle the rows and columns are numbered from 0 just like a Python list so we don't even have to bother about adding or subtracting 1. The first number starts with 1.
