Python Program to Print Pascal Triangle

Write a Python program to print a pascal triangle number pattern using for loop.

from math import factorial

rows = int(input("Enter Pascals Triangle Number Pattern Rows = "))

print("====Pascals Triangle Number Pattern====")

for i in range(0, rows):
    for j in range(rows - i + 1):
        print(end = ' ')
    for k in range(0, i + 1):
        print(factorial(i)//(factorial(k) * factorial(i - k)), end = ' ')
    print()

This Python example program prints the pascal triangle of numbers using a while loop.

# using while loop
from math import factorial

rows = int(input("Enter Rows = "))

print("====Pattern====")
i = 0
while(i < rows):
    j = 0
    while(j <= rows - i):
        print(end = ' ')
        j = j + 1
    k = 0
    while(k <= i):
        print(factorial(i)//(factorial(k) * factorial(i - k)), end = ' ')
        k = k + 1
    print()
    i = i + 1

Enter Rows = 9
====Pattern====

        1 2 1 
       1 3 3 1

     1 5 10 10 5 1
