Regarding some smart tutorial, someone already suggested this:
https://goalkicker.com/PythonBook/
In my opinion is one of the best Python book ever written, and it is completely free!

You see, you repeat at each iteration the same pattern.
Increase n, then print each line from n to 5.
for j in range(...) can be replaced by:
for j in range(5 - n), you see ?
You only need tow nested loops, one incrementing n, and the second with j.
I will give you my code if you find the way.

Sure!
Central idea of both implementations is the star operator ("iterable unpacker"), which transform a list of elements in a sequence of elements.
So:
print(*[1,2,3]) becomes print(1,2,3)
The list is created using the range() function.
In my implementation, I used the "list comprehension" syntax, used for generating a list l1 starting from another list l:
l1 = [ f(x) for x in l]
In my initial line, I tried only one print on a list of lists, starting a new line at every new element. Something like:
print(*[ *[1,2,3,4], *[2,3,4], *[3,4], *[4]], sep='\n')
This means two nidified list comprehensions.
Unfortunately we cannot use the star inside a list comprehension, so I separated the elements passing from int to str (map) and rejoining them with spaces.
Better and more readable solution: only one list of many prints:
[print(*range(n,5)) for n in range(1,5)]

Михаил Горчанюк your program is printing a wrong pattern
