Created by Guido van Rossum and first released in 1991, Python has a design philosophy that emphasizes code readability, notably using significant whitespace.

    "  ...In December 1989, I was looking for a \"hobby\" programming project\n",
    "  that would keep me occupied during the week around Christmas. \n",
    "\n",
    "  My office ... would be closed, but I had a home computer, \n",
    "  and not much else on my hands. \n",
    "  \n",
    "  I decided to write an interpreter for the new scripting language \n",
    "  I had been thinking about lately: a descendant of ABC that would \n",
    "  appeal to Unix/C hackers. \n",
    "  \n",
    "  I chose Python as a working title for the project, \n",
    "  being in a slightly irreverent mood (and a big fan \n",
    "  of Monty Python's Flying Circus).\n",
