      Python Programming Concepts - MRB

      Synopsis

      History:

      Python was created by Guido van Rossum and first released in 1991. It's named after the British comedy group Monty Python. Python's design philosophy emphasizes code readability and simplicity, with a significant focus on productivity and ease of use.

      Features:

      Readable and Expressive Syntax: Python's syntax is designed to be easy to read and write, resembling pseudo-code, which makes it particularly suitable for beginners and experienced programmers alike.

      Interpreted Language: Python is an interpreted language, which means that code written in Python is executed line by line by the Python interpreter.

      Dynamic Typing: Python uses dynamic typing, allowing variables to be declared without specifying their type explicitly. The type of a variable is determined at runtime.

      Extensive Standard Library: Python comes with a vast standard library that provides modules and functions for a wide range of tasks, from file I/O to networking to web development.

      High-level Language: Python abstracts away many low-level details, enabling developers to focus more on solving problems rather than managing memory or system resources.

      Syntax:

      Python syntax is known for its simplicity and readability.

      Some key syntax features include:

      •  Indentation-based block structure (no curly braces)

      •  Dynamic typing

      •  Comprehensive standard library

      •  Strong support for object-oriented, procedural, and functional programming paradigms

      •  Extensive support for third-party libraries and frameworks

      •  Applications: Python is used in various domains and applications

      Before we start:

      The first thing to do is to get an editor for writing the programs. There are two ways to get an editor. One an online editor and the other to install the software.

      The second option is recommended because to understand a language it is best to install the software or editor that goes with it. Online editors have limitations depending upon the provider and does require the programmer to be online.

      The software to install is available at http://www.python.org.

      Download and install the version for your computer. Note there are two versions (64 bit and 32 bit) for Windows machines.

      Overall, Python's simplicity, versatility, and strong community support have contributed to its widespread adoption in various industries and domains.

      First Program

      The first program written in every programming class is one to display the words Hello World. It is an unwritten tradition. In this regard start the Python editor from windows apps.

      The editor can be started with by clicking the IDLE Python option as shown in the above picture. The editor looks like a notepad file with a menu on top.

      Python 3.10.5 (tags/v3.10.5:f377153, Jun 6 2022, 16:14:13) [MSC v.1929 64 bit (AMD64)] on win32

      >>> greetings =Hello World!!

      >>>print(greetings) HelloWorld!!

      >>>print(Hello World)

      Hello World

      In the code above there are two ways to print Hello World to the screen. The first is to start with a variable called greetings which has the string value of Hello World followed by a print statement that prints the values of the variable. Note the brackets in the print statement.

      The second method is a direct print statement where the string is inside the brackets within double quotes.

      Thus, the tradition of printing Hello World has been completed using Python. This method will work irrespective of the version of python interpreter downloaded.

      The above code was written directly
