Python Tutorial

Python Introduction

Python is an object-oriented and high-level general-purpose programming language. In programming, Python is considered one of the most popular languages. Python’s design emphasizes code readability with its notable use of whitespace. Its language constructs and object-oriented approach aim to assist programmers to write clear, logical code for small and big-scale projects. In December 2020 Python ranked third in TIOBE’s index of most popular programming languages, which shows its use in the modern programming world.


Python was 1st released in 1991 but it was created in the late 1980s by the great programmer Guido van Rossum. This programming language keeps updating and introducing new features with time. The main 3 updated versions with their subdivisions were introduced. The first updated version 1.0 was released in January 1994.

The major new features included in this release were the functional programming tools. The next version python 2.0 with some new features was released on October 16, 2000, including a cycle-detecting garbage collector and support for Unicode. Many updated versions were introduced in between with new names. Again on December 3, 2008, Python 3.0 was introduced with its latest changes. It remained a multi-paradigm language. The updated details were intended to be faster and reliable in Python 3.0 than they were in Python 2.x. Python is expanding day by day in its advancement.


Python is a free open source dynamic and interpreted programming language. It supports object-oriented and procedural oriented programming.
Python is a dynamically typed language because we don’t need to declare the type of variable.
For example, a = 20
Here, a can be anything such as String, int, etc.

The main features are given below


Following are the main advantages of Python , discussed below,

  • Easy to learn.
  • Presence of third-party modules.
  • User-friendly data structures.
  • Portable and Interactive.
  • Extensive support libraries.
  • Portable across Operating systems.
  • Dynamically typed language.
  • Open source and community development.
  • Provide database connectivity.
  • Improves programmer productivity.


There are also some disadvantages related to Python programming given below,

  • Python is slow at run time.
  • It can’t be used for mobile application development.
  • Need more maintenance of application/code.
  • Because it’s dynamically typed language, It consumes more memory.
  • It has limitations with database access.

Applications based on Python

There are many applications which are based on python such as

  • Web frameworks
  • Web applications
  • Prototyping
  • Graphic user interface applications
  • Software developments
  • Operating systems


Python could be a broadly utilized language for mechanization scripts as the scripting language. Each language is having its own advantages and drawbacks. Python is presently the foremost well-known language to utilize over the organization and software engineers as well. It underpins cross-platform and applications based on python language can be run on any stage without any issues. For Python, Python 2 and Python 3 adaptations are more well known within the showcase to utilize. Python 3 has appeared an incredible alter within the field of programming languages for python. In this form, the capacities ended up more basic, and unused add-on things got included that create it consistent with lower forms and application for python.
