The Story of 1 is a BBC documentary about the history of numbers, and in particular, the number 1. It was presented by former Monty Python member Terry Jones . It was released in 2005.
The reference count of a string is checked before mutating a string. This allows reference count 1 strings to be mutated directly whilst higher reference count strings are copied before mutation. This allows the general behaviour of old style pascal strings to be preserved whilst eliminating the cost of copying the string on every assignment.

The Swiss Federal Railways number certain classes of rolling stock from zero, for example, Re 460 000 to 118. In the realm of fiction, Isaac Asimov eventually added a Zeroth Law to his Three Laws of Robotics, essentially making them four laws. A standard roulette wheel contains the number 0 as well as 1-36. It appears in green, so is classed as ...
The Funniest Joke in the World" (also "Joke Warfare" and "Killer Joke") is a Monty Python comedy sketch revolving around a joke that is so funny that anyone who reads or hears it promptly dies from laughter. Ernest Scribbler (Michael Palin), a British "manufacturer of jokes", writes the joke on a piece of paper only to die laughing.
In mathematics, the prime-counting function is the function counting the number of prime numbers less than or equal to some real number x. [1] [2] It is denoted by π(x) (unrelated to the number π). A symmetric variant seen sometimes is π 0 (x), which is equal to π(x) − 1 ⁄ 2 if x is exactly a prime number, and equal to π(x) otherwise.
Python supports normal floating point numbers, which are created when a dot is used in a literal (e.g. 1.1), when an integer and a floating point number are used in an expression, or as a result of some mathematical operations ("true division" via the / operator, or exponentiation with a negative exponent).
Python 2.0 was released on October 16, 2000, with many major new features, such as list comprehensions, cycle-detecting garbage collector (in addition to reference counting) and reference counting, for memory management and support for Unicode, along with a change to the development process itself, with a shift to a more transparent and ...
