what does the output "<generator object <genexpr> at 0x0000020B9232B888>" mean in python-3? -

code:

marks = [[ input() , float(input()) ] _ in range(int(input()))]  s = ( y [x,y] in marks)  print(s)  l = list(s) l.sort()   print(l)  sec = l[1] ans = [x [x,y] in marks if y == sec]  ans.sort() x in ans: print(x) 

output:
