For example:
                    

# Python program to print pascal's triangle

from math import factorial

# input value of n

n = 5

#uncomment this line to take input from user

#n=int(input("Enter the value of n: "))

for i in range(n):

    for j in range(n-i+1):

        # for spacing

        print(end=" ")

    for j in range(i+1):

        # nCr formula      

print(factorial(i)//(factorial(j)*factorial(i-j)), end=" ")

    # for new line

print()

Output:

      

                    

      1
