Pascal's Triangle for Python

Question

As a learning experience for Python, I am trying to code my own version of Pascal\'s triangle. It took me a few hours (as I am just starting), but I came out with this code:

Answer 1

Here is a simple way of implementing the pascal triangle:

def pascal_triangle(n):
    myList = []
    trow = [1]
    y = [0]
    for x in range(max(n,0)):
        myList.append(trow)
        trow=[l+r for l,r in zip(trow+y, y+trow)]

    for item in myList:
        print(item)

pascal_triangle(5)

Python zip() function returns the zip object, which is the iterator of tuples where the first item in each passed iterator is paired together, and then the second item in each passed iterator are paired together. Python zip is the container that holds real data inside.

Python zip() function takes iterables (can be zero or more), makes an iterator that aggregates items based on the iterables passed, and returns the iterator of tuples.
