Pascal’s triangle is a useful recursive definition that tells us the coefficients in the expansion of the polynomial (x + a)^n. If we have the a row of Pascal's triangle, we can easily compute the next row by each pair of adjacent values. In much of the Western world, it is named after the French mathematician Blaise Pascal, although other mathematicians studied it centuries before him in India, Persia, China, Germany, and Italy.. from toolz import memoize, sliding_window @memoize def pascals_triangle (n): """Returns the n'th row of Pascal's triangle.""" First, the default argument m=1 is awkward, which leads to the odd if m > n+1: and if m == 1: test conditions. 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.
