Python Pattern Programs - Printing Stars in Hollow Right Triangle Shape

agr * do bar call karega to kya ye extra memory use krega

Why we are taking 0,n why not n

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

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()

Thanks ❤️

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

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()

not getting proper output

good explanation

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()

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

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()

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

Using one for loop and r.just:
n = int(input("Enter number of rows: "))
for i in range(1,n+1):
if i ==1:
print("*"*n)
elif i == n:
print("*".rjust(n," "))
else:
print("*".rjust(i, " ") + "*".rjust(n-i," "))

Please make video in hindi

Thank you so much, your content is helping me a lot these days👏👍

can you do this
Right Angled Triangle - 3
Given an integer number N as input. Write a program to print the right-angled triangular pattern of N rows as shown below.

Input
The first line of input is a positive integer.

Explanation
For example, if the given number is 5, the output should be

Sample Input 1
Sample Output 1
- - - - - -
| /
| /
| /
| /

But I am getting this ****

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()

nice 👍🏻👍🏻👍🏻

Best teaching👍

How about parallelogram shape? can it also be constructed?

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!

Program will be not run python 3.0

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()

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?

Can u please make video for practice programs in Dictionary... I want to learn how to write programs in dictionary from u... U explain really good... Please help.!

Best tutor...

Nice teaching...

Hi can u send me same program with no space in between but in same shape

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

output is totally diff. can you plz resolve it .

Its not working plz provide proper code

This logic doesn't works I am not getting require out put

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

Hi Amulya ur beautiful teaching

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

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

thank you mam
