In mathematics, one of the most interesting number patterns is Pascal’s Triangle. It is named after Blaise Pascal (1623 – 1662), a famous French Mathematician and Philosopher.

To build a Pascal Triangle we start with a “1” at the top. We then place numbers below each number in a triangular pattern: Each number is the result of adding the two numbers directly above it. (See animation)

For this challenge we will use a Python script to output a Pascal Triangle after a fixed number of iterations (rows): e.g.

To do so we will use the following programming concepts:

**Iteration**: Each iteration will output one line of the triangle**List**: We will use a list to store all the values appearing on one row**String Manipulation**: We will use string manipulation techniques to format the output printed on screen (e.g. Our Pascal Triangle should appear centered on screen)

#### Python Code

We have started the code for you. You will need to complete this code form line 20.
