Thank you for this.

I just wanted to point out a few things which might make it easier for everyone:

1. Using a list to store the lowercase alphabet is not required; you can just use a string.
2. Related to #1, rather than use list(map(chr, range(97, 123))), you can just import string and use the built-in string.ascii_lowercase.

alphabet = string.ascii_lowercase
alphabet_subset = alphabet[size-1::-1] + alphabet[1:size]
width =

for i in range(1, size):
+ alphabet[size-i:size]).center(width, "-"))

for i in reversed(range(1, size + 1)):
+ alphabet[size-i:size]).center(width, "-"))

Thanks so much. Your thinking is so good that half the video I stopped watching it and implemented the solution by my own - following your idea- and it worked.

I never subscribe to any channel but the way you explain the question so simply and also put effort by using a drawing board to explain the concept. Also if you can speak hindi then you should also make content in hindi for the mass indian audience

One shortcut we can use m=4*n-3 to get the width of the pattern
