14 # https://mail.python.org/pipermail/python-list/2001-December/093408.html
15 # [2/8/25, 23:28:55] Fernando Perez: All that started two months earlier
16 # - in October 2001 I read this article:
17 # [2/8/25, 23:28:55] Fernando Perez:
18 # https://web.archive.org/web/20011202000624/http://www.onlamp.com/pub/a/python/2001/10/11/pythonnews.html
19 # [2/8/25, 23:29:05] Fernando Perez: Which is also archived here:
20 # [2/8/25, 23:29:05] Fernando Perez:
21 # https://docstore.mik.ua/orelly/weblinux2/orn/interactive_python.html
22 # [2/8/25, 23:29:48] Fernando Perez: That article put me on the trail of
23 # LazyPython, and I also found out (can’t remember where) about IPP
24 # (Interactive Python Prompt), another similar projecd by Janko Hauser.
25 # [2/8/25, 23:30:20] Fernando Perez: A also read an article around that
26 # time, about new features in Python 2.0, which spoke of how
27 # sys.displayhook could be programmed to call any object you wanted.
28 # [2/8/25, 23:31:01] Fernando Perez: Those things together gave me the
29 # idea of implementing a stateful object, the “IPython Prompt”, that
30 # could store a cache of old results, Mathematica-style, and that could
31 # have all kinds of other useful tricks up its sleeve.
32 # [2/8/25, 23:31:17] Fernando Perez: I can’t remember if I did the
33 # prompt stuff first and then read about LazyPython/IPP.
34 # [2/8/25, 23:31:41] Fernando Perez: I do know that, implementation
35 # wise, at first I just did the tiny IPython 0.0.1 that I posted much
36 # later on github as a gist:
37 # [2/8/25, 23:31:55] Fernando Perez:
38 # https://gist.github.com/fperez/1579699
39 # [2/8/25, 23:32:03] Fernando Perez: But I only shared that publicly
40 # much later.
41 # [2/8/25, 23:33:19] Fernando Perez: I did find out about IPP/LazyPython
42 # sometime in October, contacted Janko and Nathan who told me to use
43 # their code at will but said they were busy with other things, and got
44 # cranking for a few mad weeks on what became the IPython 0.2.0 that I
45 # posted about in that comp.lang.python thread of December 2001.
46 # [2/8/25, 23:33:52] Fernando Perez: That period from Oct 11 to Dec 9
47 # 2001 was maniacal coding, with very little sleep 🙂
