2: Pascal’s Triangle Number Pattern Program in Python

def pascal(n):
    for i in range(0, n):
        for j in range(0, i + 1):
            print(function(i, j)," ", end="")
        print()

def function(n, k):
    res = 1
    if (k and n - k):
        k = n - k
    for i in range(0, k):
        res = res * (n - i)
        res = res // (i + 1)

    return res

1  6  15  20  15  6  1    

3: Half-Pyramid Pattern Program Python With Numbers

def pattern(n):
    k = 2 * n - 2
    x = 0
    for i in range(0, n):
        x += 1
        for j in range(0, k):
            print(end=" ")
        k = k - 1
        for j in range(0, i + 1):
            print(x, end=" ")
        print("")
    k = n - 2
    x = n + 2
    for i in range(n, -1, -1):
        x -= 1
        for j in range(k, 0, -1):
            print(end=" ")
        k = k + 1
        for j in range(0, i + 1):
            print(x, end=" ")
        print("")

pattern(5)

Output

        1
       2 2
      3 3 3
     4 4 4 4
    5 5 5 5 5
   6 6 6 6 6 6
    5 5 5 5 5
     4 4 4 4
      3 3 3
       2 2
        1 

4: Number Descending Order Pattern Program in python

def pattern(n):
    for i in range(n, 0, -1):
        for j in range(1, i + 1):
            print(j, end=" ")

        print("")

pattern(5)

Output

1 2 3 4 5
1 2 3 4
1 2 3
1 2
1 

5: Binary Numbers Pattern Program in python

def pattern(n):
    k = 2 * n - 2
    for i in range(0, n):
        for j in range(0, k):
            print(end=" ")
        k = k - 1
        for j in range(0, i + 1):
            print('10', end="")

        print("&#92r")

pattern(5)

Output

        10
       1010
      101010
     10101010
