Python Exercise: Print out the first n rows of Pascal's triangle
Python Functions: Exercise-13 with Solution
Write a Python function that prints out the first n rows of Pascal's triangle.
Note : Pascal's triangle is an arithmetic and geometric figure first imagined by Blaise Pascal.
Sample Pascal's triangle :

Each number is the two numbers above it added together
Sample Solution :-
Python Code :
def pascal_triangle(n):
trow = [1]
y = [0]
for x in range(max(n,0)):
print(trow)
trow=[l+r for l,r in zip(trow+y, y+trow)]
return n>=1
pascal_triangle(6)
Sample Output:
[1] [1, 1] [1, 2, 1] [1, 3, 3, 1] [1, 4, 6, 4, 1] [1, 5, 10, 10, 5, 1]
