[CrusaderT]

Can someone please explain the syntax and the logic of the below code? Especially the first line.

How many stars (*) will the following snippet send to the console?

lst = [[c for c in range(x)] for x in range(3)] for x in lst: for y in x: if y < 2: print('*', end='')

The first line is called a list comprehension. If you don't understand the rest of the code, how have you been learning?

[CrusaderT]

The rest I understand. Thanks. Will look into list comprehensions.
