Print Pattern Python

PROGRAM TO PRINTING PYRAMID PATTERN USING RECURSION

# function to print a row

def printn(num):

      

    # base case

    if (num == 0):

        return

    print("*", end = " ")

  

    # recursively calling printn()

    printn(num - 1)

  

# function to print the pattern

def pattern(n, i):

      

    # base case

    if (n == 0):

        return

    printn(i)

    print("\n", end = "")

      

    # recursively calling pattern()

    pattern(n - 1, i + 1)

  

# Driver Code

if __name__ == '__main__':

    n = 5

    pattern(n, 1)
