RULES :

• In the outer loop , count the no of lines
• For the inner loop , focus on columns & connect them somehow to the rows
• Print them “*” middle of the inner loop
• Observe Symmetry

PATTERN -1:

'''

'''

# outer loop -> 4 times (since it has 4 lines)
for i in range(5):
    # inner loop -> 7 columns (7 times print * in the same line)
    for j in range(7):
        print('*', end=" ")
    print( ) 

PATTERN -2:

def nForest(n:int) ->None:
    # n rows
    for i in range(n):
				# for each row -> (no of cols =  row_num )
        for j in range(i+1):
            print('*',end=' ')
        print()

def seeding(n: int) -> None:

    for i in range(n):
				# connect cols with row
        for j in range(n-i):

        print()

code :
num_rows = 4
for i in range(0, num_rows):
	for j in range(0, num_rows-i-1):
		print(end=" ")
	for j in range(0, i+1):
		print("*", end=" ")
	print()
