On: Show HN: Pyp – Easily, magically, run Python at the shell

There are a number of possible options! And remember you can always pipe pyp to pyp. Here are some ideas, in order of what came to mind, where the operation is incrementing.

  pyp 'lines[lines.index("start") + 1:]' | pyp 'lines[:lines.index("end")]' | pyp 'int(x) + 1'
  
  pyp 'start = lines.index("start"); end = lines.index("end", start); map(lambda x: int(x) + 1, lines[start + 1:end])'
  
  pyp 'dropwhile(lambda x: x != "start", lines)' | pyp 'lines[1:]' | pyp 'takewhile(lambda x: x != "end", lines)' | pyp 'int(x) + 1'
  
  pyp 'map(lambda x: int(x) + 1, takewhile(lambda x: x != "end", islice(dropwhile(lambda x: x != "start", lines), 1, None)))'
  
  pyp -b 'cond = False' 'if cond and x == "end": break' 'if cond: print(int(x) + 1)' 'if x == "start": cond = True'
