[code python] [z for b in a for c in b for d in c … for z in y] Which would be like having this regular for-loop:

for b in a:

  for c in b:
      for d in c:
          ...
              for z in y:
                  # have z

[/code]

[code python] list(set(sorted([v for i in [dict(parser.items(x)) for x in parser.sections()] for k,v in i.items() if k.startswith('group')]))) [/code]

[code python] vec = 1,2,3], [4,5,6], [7,8,9 print [num for elem in vec for num in elem] ←—- this

[1, 2, 3, 4, 5, 6, 7, 8, 9]
