In essence, Python is an advanced programming language. Its nature is that of a dynamic, free, open-source language. Additionally, it transforms the source code into machine code using an interpreter. It additionally facilitates procedure-oriented and object-oriented programming. It's a very legible language that makes use of English keywords.

Evolution of Python

Python was created by Guido Van Rossum in the middle of the 1980s and 1990s. It was created by him at the Netherlands' National Research Institute for Mathematics and Computer Science.

Numerous languages, including C, C++, Algol-68, ABC, Unix shell, etc., are its ancestors. It is also protected by copyright.

Features

The characteristics are as follows:

• Simple to maintain and code
• Because it's so simple to learn, it's frequently referred to as developer-friendly. In addition, we can quickly become proficient at writing its code in a matter of hours or days. Furthermore, this is made feasible by its short list of keywords, straightforward structure, and unambiguous syntax.

Free and open-source

Anyone can download, use, and distribute this language because it is open-source. In addition, it is free.

Oriented on objects

It is compatible with aspects of object-oriented programming languages. For example, the concept of object and classes, encapsulation, inheritance, etc.

Facilitates GUI programming

Python allows you to create a variety of graphical user interfaces. Moreover, these programs are compatible with a wide range of system programs and libraries. Additionally, it contains modules that allow us to create graphical user interfaces, such as PyQt5, PyQt4, wxPython, or Tk. The most widely used one among them to create graphical applications is PyQt5.

Broad in scope

Because of its expandable nature, Python code can be used in other languages. For instance, code written in C or C++ can also be compiled in C.

Both transportable and platform-neutral

It is designed to be portable. Additionally, we don't need to modify the Python code to run it in any environment—Windows, Linux, Mac, etc.

Combined Language

It is simple to combine with other languages, like C, C++, etc. It is an integrated language as a result.

Language Interpretation

It transforms the source code into machine code using an interpreter. This indicates that the Python code is being run line by line. As a result, debugging and fixing the mistake become simple.

Massive Standard Library

Python has an enormous amount of libraries. These libraries include pre-built functions and modules for certain tasks. Because he doesn't have to accomplish everything by himself, the programmer can write code more easily. Additionally, the library is cross-platform compatible and portable.

Dynamically Typed

This implies that the variable's type need not be defined. At run time, the interpreter makes this decision on its own. Thus, the name was typed dynamically.

Adaptable

It offers strong assistance for extensive programs.

In addition to this, some other features are as follows:

• Programming structures that are procedure-oriented and object-oriented are both supported.
• It is a scripting language that can be used for complex applications.
• It has an automated waste collection system.
• It checks types dynamically.
• Sensitive in terms of the case.
• Beneficial when creating web applications.
• It organizes the program using indentation. As opposed to other languages where blocks are distinguished using brackets.

Python Execution Modes

Python, as we all know, employs an interpreter to run source code. There are currently two methods for utilizing the interpreter. They are listed in the following order:

Engaging Mode

Script Mode

We can quickly run a single sentence in the interactive mode. On the other hand, we can write and run numerous lines of code in script mode.

Engaging Mode

We can only run one statement at a time in this manner. Additionally, we must write the phrase in front of '>>>' and hit enter in order to use the interactive mode. This instantly produces that specific statement's output. Using this option to view the instant output is simple and convenient. 

However, in order to execute the code, we must write it again because we are unable to preserve it in its entirety.

Script Mode

The entire source code must be written in this mode and saved as a Python source code file. Additionally, we may use the interpreter to run this file. Additionally, the Python source code file is saved with the extension “.py.”
