Learn Python

Python originally means “Python”. In 1989, Dutchman Guido Van

Rossum invented an object-oriented interpretive high-level programming language called Python. Python’s design philosophy was elegant, unambiguous, and simple. In fact, Python has stuck to this philosophy so far that the phrase “Life is short, I use Python” is now widely used on the Internet. Python is simple, fast to develop, time saving, and easy to learn.

Python is a cross-platform computer programming language. Is a high-level scripting language that combines interpretability, compilation, interactivity, and object-oriented programming. Originally designed for writing automated scripts (shells), it has gradually been used for independent, large-scale project development as versions are updated and new features of the language are added.

In 2020, Google and tech giants like Reddit, Facebook, PayPal, Instagram, Netflix, and Dropbox chose Python as the coding language. But achieving this kind of success is not easy. Python illustrates this achievement by being a multipurpose language that can be used for any programming task: mobile and Web application development, scientific computing, game development, and systems administration. Whether you’re looking to join the IT department as a coder or Python

Anyone interested in Web development needs to understand why Python continues to thrive.

In 2021, the Python programming language will celebrate its 30th anniversary. In the niche market, Python completed three decades of growth, making most other programming languages outperform, growing 456%.

2. Python application domain

Python, as a powerful programming language, is favored by many developers because it is easy to learn. So, what are Python’s application areas?

In summary, there are several main areas of Python application.

  • **Web application development **
  • Big data processing
  • Automated operation and maintenance
  • Artificial intelligence
  • Web crawler
  • Cloud computing
  • The game development
