The development of Python occurred at a time when many other dynamic (and open-source) programming languages such as Tcl, Perl, and (much later) Ruby were also being actively developed and gaining popularity. To help put Python in its proper historical perspective, the following list shows the release history of Python. The earliest dates are approximate as I didn't consistently record all events:

| December, 1989 | Implementation started |
| 1990 | Internal releases at CWI |

I've added hyperlinks to the releases that are still being advertised on python.org at this time. Note that many releases were followed by several micro-releases, e.g. 2.0.1; I haven't bothered to include these in the table as otherwise it would become too long. Source tarball of very old releases are also still accessible, here: http://www.python.org/ftp/python/src/. Various ancient binary releases and other historical artefacts can still be found by going one level up from there.
