Python Programming Language Python is a high-level, general-purpose programming language. Its design philosophy emphasizes code readability with the use of significant indentation. Python was conceived in the late 1980s by Guido van Rossum at Centrum Wiskunde & Informatica (CWI) in the Netherlands. Python was first released in 1991. Guido van Rossum began working on Python in the late 1980s as a successor to the ABC programming language. He chose the name Python because he was a fan of the British comedy series "Monty Python's Flying Circus." Python consistently ranks as one of the most popular programming languages. It is used for web development, data science, artificial intelligence, scientific computing, and automation. Key features of Python include: - Dynamic typing and binding - Built-in data structures like lists, tuples, and dictionaries - Support for modules and packages - Extensive standard library - Support for multiple programming paradigms Python 2.0 was released on October 16, 2000. Python 3.0 was released on December 3, 2008. Python 2.7 reached end of life on January 1, 2020. The Python Software Foundation (PSF) is a non-profit organization that holds the intellectual property rights behind Python and organizes PyCon. World War I World War I, often abbreviated as WWI, was a global conflict that lasted from 1914 to 1918. It was one of the deadliest conflicts in human history. The war was triggered by the assassination of Archduke Franz Ferdinand of Austria-Hungary on June 28, 1914, in Sarajevo by Gavrilo Princip. Several factors contributed to the outbreak of World War I: - Militarism: The buildup of military forces and arms race between nations - Alliances: Complex web of alliances that drew nations into conflict - Imperialism: Competition for colonies and global influence - Nationalism: Strong national pride and desire for independence The major Allied Powers included France, the United Kingdom, Russia, Italy, and later the United States. The Central Powers included Germany, Austria-Hungary, the Ottoman Empire, and Bulgaria. The war ended on November 11, 1918, when an armistice was signed. The Treaty of Versailles was signed on June 28, 1919, officially ending the war. An estimated 9 million soldiers and 7 million civilians died as a result of the war, making it one of the deadliest conflicts in history.
