        if (i + j) % 4 == 0 or (i == j):
            print("*", end=" ")

I am not getting the logic how to build, can you solve

The whole purpose of this problem is that you figure out the logic, or at least part of it.
If you are blank, have a talk with your teacher.

for i in range(10):
for j in range(3):
if (i == j):
print("*", end=" ")
else:
print(" ", end=" ")
print()

here my code can you suggest when get the loop

Ther entire point of the assignment is to get you to think about the problem, the pattern you see.

Nobody can do that for you.

Let's have a variable r that counts the rows, starting from zero, so that

at first row r = 0
at second row r = 1
...

Now let's have another variable c that contains the column of the '*', so that

at 1st row r = 0, c = 0
at 2nd row r = 1, c = 1
at 3rd row r = 2, c = 2
at 4th row r = 3, c = 1
at 5th row r = 4, c = 0
at 6th row r = 5, c = 1
at 7th row r = 6, c = 2
...

Do you spot the pattern ? :-D
Is there a relation between the value of r and the one of c ?

First of all, your code is too complicated!
No matter what, each output line ends with a '*'
This makes this code:

Python

for i in range(10):
    # here you just need to tell how many spaces
    Spaces= i
    for j in range(Spaces):
        print(" ", end=" ")
    print("*", end=" ")
    print()

After that, you need to get the way to tell how many spaces you want.
Partial solutions:

Python

Spaces= i % 3

Python

Spaces= 5- i % 5

Study the abs() function

While we are more than willing to help those that are stuck, that doesn't mean that we are here to do it all for you! We can't do all the work, you are either getting paid for this, or it's part of your grades and it wouldn't be at all fair for us to do it all for you.

So we need you to do the work, and we will help you when you get stuck. That doesn't mean we will give you a step by step solution you can hand in!
Start by explaining where you are at the moment, and what the next step in the process is. Then tell us what you have tried to get that next step working, and what happened when you did.

If you are having problems getting started at all, then this may help: How to Write Code to Solve a Problem, A Beginner's Guide[^]

[edit]
If it helps, this is a simple problem: I just thought for a minute and then wrote the code in C# - it needed three lines of code once you have the input value, is all. So in Python, it should be pretty easy. Think about what you are being asked to do and it should be pretty obvious.

Hello this is Gulshan Negi
Well, you need to run below code what you are looking for.

for i in range(11):
    for j in range(3):
        if (i + j) % 4 == 0 or (i + j) % 4 == 3:
            print("*", end=" ")
        else:
            print(" ", end=" ")
    print()

Thanks
