Python is an open-source programming language. It was made as a language that is both easy to work on and understand.[31] It was made by a Dutch programmer named Guido van Rossum in 1991, who named it after the television program Monty Python's Flying Circus.
Python is an interpreted language. This means it does not need to be compiled before running. A program called an interpreter runs Python code on almost any computer. So, a programmer can change the code and quickly see what happens. But this also makes Python slower than compiled languages like C, because it is not changed into machine code before running. Instead, this happens while the program is running.
Python is usually used for making websites, automating common tasks, and making charts and graphs. Since it's simple to learn, people who are not computer experts, like bookkeepers and researchers, often learn Python.
Its standard library is made up of many functions that come with Python when it is installed.[32] On the Internet, there are many other libraries libraries have been examined to provide wonderful ends in varied areas like Machine Learning (ML), Deep Learning, etc.[33] These libraries make it a powerful language; it can do many different things.
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 CPython, the main version of Python, even if the patches would make it faster. When speed is important, a Python programmer can write some of the program in a different language, like C, or use PyPy, a different kind of Python that uses a just-in-time compiler.
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. Tutorials often take a playful approach, such as referring to spam and eggs instead of the standard foo and bar.
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.[34]
Python's statements include:
x = 2
x = 'spam'
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!")
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 x was a number or a word before C would let the programmer set up x, and after that, C would not allow its type to change from a number to a word.
x
In Python they have easy to use functions. In a language like C you need to tell if it would give you back a number or word. In Python you don't have to specify the type.
def greeting(name): return "Hello, " + name print(greeting("Reader"))
When called, this function returns "Hello, Reader", which is then printed to the screen.
even though the design of C is far from ideal, its influence on Python is considerable.
It is a mixture of the class mechanisms found in C++ and Modula-3
replace "CLU" with "Python", "record" with "instance", and "procedure" with "function or method", and you get a pretty accurate description of Python's object model.
The C3 method itself has nothing to do with Python, since it was invented by people working on Dylan and it is described in a paper intended for lispers
We want something as usable for general programming as Python [...]
The Swift language is the product of tireless effort from a team of language experts, documentation gurus, compiler optimization ninjas, and an incredibly important internal dogfooding group who provided feedback to help refine and battle-test ideas. Of course, it also greatly benefited from the experiences hard-won by many other languages in the field, drawing ideas from Objective-C, Rust, Haskell, Ruby, Python, C#, CLU, and far too many others to list.
its design has also been influenced by Oberon, Rust, Swift, Kotlin, and Python.
