Concentric square pattern in Python with explanation part 2 || #ProgrammingKnowledge

Hello friends!!
Welcome to our you tube channel "Programming Knowledge".

In this video, I have described the logic and the program of concentric square pattern in Python.

What is concentric square pattern:
Concentric square pattern is a rectangular pattern in a 2D matrix in such a way that they are concentric to each other.

4 4 4 4 4 4 4
4 3 3 3 3 3 4
4 3 2 2 2 3 4
4 3 2 1 2 3 4
4 3 2 2 2 3 4
4 3 3 3 3 3 4
4 4 4 4 4 4 4

There are so many methods for printing this pattern.
In this video, I found minimum value form the index i, j, size-1-i, size-1-j.

Here is the code with list comprehension:
[print(''.join(str(n-min(i,j,high-i-1,high-j-1)) for i in range(high))) for j in range(high)]

If you know another method to print this pattern then comment below.

I hope you got the logic and the program, if you have any other doubts then feel free to ask in comment section.
Also, there are lots of other techniques to print this patter.

If you want other methods to print this pattern then comment below.
I will make second part of this video.

Hello guys!
You can apply the same logic for this pattern too:

n = int(input("enter the num"))
k = (2 * n) - 1
low = 1
high = k + 1
a = 1
b = 1

for i in range(low, high):
for j in range(low, high):
if i == a and j == b:
print(n, end=' ')
b = b + 1
if i > j:
n = n-1
if i > low and k - a < j < k:
n = n + 1

b = 1
a = a + 1
print()
