Python 3.0 was developed with the same philosophy as in prior versions. However, as Python had accumulated new and redundant ways to program the same task, Python 3.0 had an emphasis on removing duplicative constructs and modules, in keeping with the Zen of Python: "There should be one— and preferably only one —obvious way to do it".
The Birkbeck ARC, the first of three machines developed at Birkbeck, University of London by Andrew Booth and Kathleen Booth, officially came online on this date. The control was entirely electromechanical and the memory was based on a rotating magnetic drum. [72] This was the first rotating drum storage device in existence. [73] 1948 June 21

It featured the first rotating drum storage device. [26] [27] Manchester Baby, a developmental, fully electronic computer that successfully ran a stored program on 21 June 1948. It was subsequently developed into the Manchester Mark 1, which ran its first program in early April 1949.
The IBM 1301 Disk Storage Unit, [11] announced in 1961, introduced the usage of heads having self-acting air bearings (self-flying heads) with one head per each surface of the disks. It was followed in 1963 by the IBM 1302, with 4 times the capacity. Also in 1961, Bryant Computer Products introduced its 4000 series disk drives.
Guido van Rossum began working on Python in the late 1980s as a successor to the ABC programming language and first released it in 1991 as Python 0.9.0. [36] Python 2.0 was released in 2000. Python 3.0, released in 2008, was a major revision not completely backward-compatible with earlier versions. Python 2.7.18, released in 2020, was the last ...
The machine was not intended to be a practical computer but was instead designed as a testbed for the Williams tube, the first random-access digital storage device. [113] Invented by Freddie Williams and Tom Kilburn [114] [115] at the University of Manchester in 1946 and 1947, it was a cathode-ray tube that used an effect called secondary ...
When the first microcomputers were being developed in the 1970s, the 8-inch floppy found a place on them as one of the few "high speed, mass storage" devices that were even remotely affordable to the target market (individuals and small businesses). The first microcomputer operating system, CP/M, originally shipped
