Python Program to Create Pyramid Patterns (Pascal's Triangle)

rows = int(input("Enter number of rows: "))
coef = 1

for i in range(1, rows+1):
    for space in range(1, rows-i+1):
        print(" ",end="")
    for j in range(0, i):
        if j==0 or i==0:
            coef = 1
        else:
            coef = coef * (i - j)//j
        print(coef, end = " ")
    print()

Output

         1   1
       1   2   1
     1   3   3    1
