Here is the correct code below 👇

N = int(input())
for row in range(0, N):
for col in range(0, N):
if col == N-1 or row == 0 or col == row:
print("*", end=" ")
else:
print(" ", end=" ")
print()

Thanks a lot Amula you are the best,
Update code:
rows = int(input("Enter Numbers of rows:> "))
for row in range(rows):
for col in range(rows):
if row == 0 or col == rows - 1 or row == col:
print('*', end=' ')
else:
print(' ', end=' ')
print()

Nice way of explaination. Watching 7.8.24

hi, 1stly thanks for teaching in such a brilliant way. U made python very easy to understand. Now my query is that if we write print(end="*") instead of print("*", end=""), we get the same result result then why don't we write in the first way?

Hi, what if we want space between the each star in row and get the hollow right angle triangle. Can you explain it

[victoryvertexuniverse]

I like your voice..😍and explanation take a bow.

[svvvreddy]

i tried your code i got an inappropriate output
can you suggest, mistake made by me ....
n = int(input())
for row in range(0, n):
for col in range(0, n):
if row==0 or col==(n-1) or row==col:
print('* ', end="")
else:
print(end=" ")
print()

[subbubala]

n=int(input())
for row in range (0, n):
for colu in range(0, n):
if row==colu or row==0 or colu==n-1:
print("* ", end="")
else:
print(end=" ")
print()

[stayconnectedhere]

for row in range(5) :
for col in range(5) :
if row==0 or col==4 or row==col:
print("*", end=" ")
else:
print(end=" ")
print()

Hi Amulya,


The above mentioned program doesn't work. Here's the program. Could you check?


n= int(input("enter the no of rows:"))
for r in range(0, n):
for c in range(0, n):
if r==0 or c==(n-1) or r==c:
print('*', end = '')
else:
print(end='')
print()


Thanks!

[jayantamasanta]

correct code
n = int(input('Enter an integer number: '))
for rows in range(n):
for columns in range (n):
if rows==0 or columns==(n-1) or rows==columns:
print('*', end='')
else:
print(end=' ')
print()

Madam, row and col evi = cheyalli
Space or stsrs ?

[harshvardhan]

[adityanarayannayak]

if i want space after each star how can i write the program

[satvikchaturvedi]

hey there, could you please upload a video on how to print stars in shape of right angle with no hollow space?

[jhonjhon]

please explain the else part space because they work when the if condition is wrong in this code if condition is not wrong please explain line by line working

[markcalds]

How about parallelogram shape? can it also be constructed?

[kalpatarunayak]

it does not the last line not come and plz if possible in while loop then plz give me some idea
