Python Program To Print Pascal’s Triangle (2 Ways)
In this program, we will learn how to print Pascal’s Triangle using the Python programming language.
What is Pascal’s Triangle?
In mathematics, It is a triangular array of the binomial coefficients. It is named after the French mathematician Blaise Pascal.

We will discuss two ways to code it.
- Using Factorial
- Without using Factorial
Python Programming Code To Print Pascal’s Triangle
Using Factorial
We have already discussed different ways to find the factorial of a number. So, you look up there to learn more about it.
Code:-
def fact(n): res=1 for c in range(1,n+1): res = res*c return res rows = int(input("Enter the number of rows : ")) for i in range(0, rows): for j in range(1, rows-i): print(" ", end="") for k in range(0, i+1): coff = int(fact(i)/(fact(k)*fact(i-k))) print(" ", coff, end="") print()
Ouput:-
Enter the number of rows : 5 1 1 1 1 2 1 1 3 3 1 1 4 6 4 1
Without using Factorial
Code:-
rows = int(input("Enter the number of rows : ")) for i in range(0, rows): coff = 1 for j in range(1, rows-i): print(" ", end="") for k in range(0, i+1): print(" ", coff, end="") coff = int(coff * (i - k) / (k + 1)) print()
Output:-
Enter the number of rows : 8 1 1 1 1 2 1 1 3 3 1 1 4 6 4 1 1 5 10 10 5 1 1 6 15 20 15 6 1 1 7 21 35 35 21 7 1
