Here you loop over each lines. A "while loop" is not the best way to do
this, a for loop would be much better.

When you finish this while loop, you then start a brand new while loop:

> lines = int(input('How many lines would you like?'))
All this does is repeatedly ask the user if they want to go again, over
and over and over and over again, never stopping. It never stops because
abz never gets changed: it starts with the value 0, and it stays with
the value 0 forever.
Here is how I would solve this problem in English. You can try
translating it into Python code:
start
WHILE the user wants to play:
ask how many numbers to pick
FOR each of those numbers:
print a random number
print that number
ask the user if they want to play again
end
Take note of the indentation: there is only one WHILE loop, and asking
the user if they want to play again is *inside* that while loop, not
outside it.
Hope that this helps. Please try your best to change this to Python
code, and ask for help if you need it.
