Python

Programmin

g Language

Python is the future of AI and Machine Learning.

• (^) Python numerical computation engines such as NumPy and SciPy, allowing complex calculations to be done by a single “import” statement followed by a function call.
• (^) Given the flexibility of the language, its speed, and the machine learning functionality delivered by libraries such as scikit-learn, Keras, and TensorFlow, we’ll continue to see Python dominate the machine learning landscape.

Introduction

• (^) Python interpreters are available for many operating systems.
• (^) Like Java, once written, programs can be run on any operating system.
• (^) Like other dynamic languages, Python is often used as a scripting language, but is also used in a wide range of non scripting contexts.
• (^) It has automatic memory management(Garbage collection)

History

• (^) The history of Python starts with ABC.
• (^) Python was conceptualized by Guido Van Rossum in the late 1980s.
• (^) It was in late 1980’s, when Guido van Rossum came up with an idea to develop a programming language while working in CWI(Centrum Wiskunde and Informatica), Amsterdam, for a project named Amoeba which is a distributed operating system.
• (^) ABC is a general-purpose programming language and programming environment, which had been developed in the Netherlands, Amsterdam, at the CWI (Centrum Wiskunde & Informatica).

Features of Python Easy to Read, Learn and Use(Readability):

• (^) Python does not involve the use of complex syntaxes which makes it a highly readable language.
• (^) Python's syntax is clear and readable.
• (^) It is also very easy language to learn and use in web development and GUI- based applications. Interpreted Language-
• (^) Python is an interpreted language.
• (^) It means you don’t need to compile your codes to execute the program.
• (^) Following is a list of Python Interpreters.
  • (^) CPython
  • (^) PyPy
  • (^) Stackless Python

Cont .. Interactive Language-

• (^) Python is an interactive language, which means you can write your programs in Python prompt thus enabling you to interact with the interpreter. Portable-
• (^) Since a python program has the ability to run on all platforms such as Windows, MacOS, Linux etc., thus making it a highly portable language.
• (^) It can run on various hardware platforms and has the same interface on all platforms.

Cont .. Cross-Compilation-

• (^) You can actually use python codes in other languages by means of several compilers that are listed below. - (^) Jython- compiles Python code to Java Bytecode - (^) Pyjs- compiles Python code to JavaScript - (^) Cython- compiles Python code to C and C++ - (^) Pythran- compiles Python code to C++ - (^) IronPython- it is used to run Python programs on .NET Framework.

Embeddable-

• (^) You can embed Python within your C/C++ program to give scripting capabilities for your program's users.

Cont .. Object Oriented-

• (^) Python supports procedure-oriented programming as well as object- oriented programming.
• (^) In procedure-oriented languages, the program is built around procedures or functions which are nothing but reusable pieces of programs.
• (^) In object-oriented languages, the program is built around objects which combine data and functionality. Extensible-
• (^) If you need a critical piece of code to run very fast, you can achieve this by writing that piece of code in C, and then combine that with your Python program.
