Python's developers try to avoid changing the language to make it better until they have a lot of things to change. Also, they try not to make small repairs, called patches, to unimportant parts of the CPython reference implementation that would make it faster. When speed is important, a Python programmer can move some of the work of the program to other parts written in programming languages like C or PyPy, a just-in-time compiler. It translates a Python script into C and makes direct C-level API calls into the Python interpreter.
Keeping Python fun to use is an important goal of Python’s developers. It reflects in the language's name, a tribute to the British comedy group Monty Python. On occasions, they are playful approaches to tutorials and reference materials, such as referring to spam and eggs instead of the standard foo and bar.
Python is used by hundreds of thousands of programmers and is used in many places. Sometimes only Python code is used for a program, but most of the time it is used to do simple jobs while another programming language is used to do more complicated tasks.
Its standard library is made up of many functions that come with Python when it is installed. On the Internet there are many other libraries available that make it possible for the Python language to do more things. These libraries make it a powerful language; it can do many different things.
Some things that Python is often used for are:
Python has a very easy-to-read syntax. Some of Python's syntax comes from C, because that is the language that Python was written in. But Python uses whitespace to delimit code: spaces or tabs are used to organize code into groups. This is different from C. In C, there is a semicolon at the end of each line and curly braces ({}) are used to group code. Using whitespace to delimit code makes Python a very easy-to-read language.
Python's statements include:
Python's expressions include some that are similar to other programming languages and others that are not.
This is a small example of a Python program. It shows "Hello World!" on the screen.
print("Hello World!")
ready = True
if ready:
Python also does something called "dynamic variable assignment". This means that when a number or word is made in a program, the user does not have to say what type it is. This makes it easier to reuse variable names, making fast changes simpler. An example of this is shown below. This code will make both a number and a word, and show them both, using only one variable.
x = 1
print(x)
x = "Word"
print(x)
In a "statically typed" language like C, a programmer would have to say whether codice_3 was a number or a word before C would let the programmer set up codice_3, and after that, C would not allow its type to change from a number to a word.
Back to the Future
Back to the Future is a 1985 American science fiction adventure movie directed by Robert Zemeckis and written by Bob Gale. It stars Michael J. Fox, Christopher Lloyd and Crispin Glover. It is the first movie for the "Back to the Future trilogy".
In 1985, Doc Emmett Brown shows teenage Marty his new creation: a car which can travel through time. The heart of the time machine is "the flux capacitor," invented by Dr. Brown. The time machine needs plutonium to provide the power for the flux capacitor. Marty uses the car to escape from Libyan terrorists and accidentally goes back to the year 1955. Marty seeks out and meets Dr. Brown in 1955. The time machine is out of plutonium, and there is no plutonium available for the time machine in 1955. By chance, Marty knows the time and place of a one-time natural event (lightning strike) that can provide the power to transport the time machine and Marty back to 1985.
The situation in 1955 is complicated when Marty meets his own parents as teenagers. When he helps his father, he accidentally changes the events that lead to his parents becoming a couple. Marty's teenage mother becomes interested in Marty instead of Marty's father, George. With the help of the Doc of 1955, Marty tries to undo the damage he has done, and make his mother fall in love with his father. If he can get his parents back together, he has very little time to get back to the car to use the lightning strike to take the time machine and him (Marty) back to the future (i.e. 1985).

Arthur Schopenhauer
Arthur Schopenhauer (February 22, 1788 in Danzig – September 21, 1860 in Frankfurt am Main) was a German philosopher.
He was influenced by Kant, Plato and eastern teachings, especially Buddhism and the Upanishads.
Schopenhauer believed that the primary characteristic, or essence of all things - including human beings - is not intelligence, rationality or spirit, but will. By "will" he means a wanting and craving like that which we know in ourselves as our "will." It is the source of immense amounts of suffering in the world. He also believed that a "better consciousness" could be attained by denying the fulfilment of our desires, taking time to think about who we really are and what we should do to avoid suffering - but also, in doing something few philosophers of his day spoke of: in making and looking at works of art, especially music, which he considered a way to escape from the world's pain and suffering.
Schopenhauer was a huge influence on Richard Wagner, Friedrich Nietzsche, Ludwig Wittgenstein, Thomas Mann, Sigmund Freud, Leo Tolstoy, Carl Jung, Emil Cioran and many other important artists and thinkers of the 20th Century.
2005 Cronulla riots
The 2005 Cronulla riots were a series of violent events between Lebanese and white Australian mobs. Riots started in and around Cronulla, a suburb on the beach in Sydney, Australia's biggest city. The violence was soon also in other suburbs around Sydney. The riots happened on 11, 12 and 14 December. Many people committed crimes there.
Several people were sent to prison for being involved in the riot.
1992 Los Angeles riots
The 1992 Los Angeles riots, also called Rodney King uprising or Rodney King riots, started on April 29, 1992 when a jury set four white policemen free. The jury was mostly Caucasian. The policemen had beaten up African-American motorist Rodney King badly and filmed this, after he fled from police. Thousands of people in Los Angeles, mostly African American and Hispanic, rioted. In all, 55 people were killed in the riots.
Hypotenuse
The hypotenuse is the side opposite the 90 degrees angle in a right triangle. It is always the longest side.
For example:
In this triangle, if angle C is 90 degrees, then the opposite side, "c", is the hypotenuse. The hypotenuse is important in trigonometry, where it is used to calculate many functions.
The length of the hypotenuse can be calculated if the other two sides are known, using Pythagoras' Theorem. In fact, the length of any side of a right triangle can be calculated if the other two sides are known, using this theorem.
Niðavellir
In Norse Mythology, the Niðavellir are dark fields, mentioned in the Völuspa. The dwarves live there.
Python
Python is the name given to a genus of constricting snakes. Such snakes are not venomous. its family is the "Pythonidae". Pythons are more closely related to boas than to any other snake family.
Boulenger (1890) thought this group was a subfamily (Pythoninae) of the family Boidae (boas). However, boas produce live young, while pythons are oviparous: they lay eggs.
"Python" can be found in Southeast Asia and Africa, and other members of the family are found in New Guinea and Australia. Pythons can range from 3 feet long in species like ball pythons to 29 feet in species like reticulated pythons. "Python" is one of eight genera in the family. They all have a rather similar life style.
