What is Python ?

  • Python is a high-level, interpreted, interactive programming and scripting language.
  • It processes code at runtime using the interpreter.
  • It is an cross-platform language.
  • It is supported by Windows XP to 10, Linux, Macintosh Operating System.
  • User can interact with python interpreter directly via Python Interactive >>> or Console.
  • It supports Object-Oriented Programming Style.

Who created it ?

  • Guido van Rossum in the late eighties and early nineties.

Where can it be used ?

  • Day-to-day Scripting Tasks
  • Enterprise Automation
  • Distributed Systems
  • Software Architectures
  • Cloud Computing
  • Web Services
  • Text Processing
  • Application Development
  • Web Development
  • Game Development
  • DevOps Lifecycle
  • Scientific Computing
  • Mathematics
  • Big Data Analytics
  • Media Processing
  • Machine Learning
  • Artifical Intelligence

When should I use python ?

  • Implement the Proof of Concept where "THIS WORKS" is quite important.
  • Teach the programming to kids, elderly people and non-programmers.
  • Automation or scripting for daily tasks.
  • Quickly develop and deliver.
  • Leisure projects for fun
  • Experimenting stuff which is additional activity.
  • Where there are too many unknowns, community comes to rescue.

Why should I use python ?

  • Free and open source
  • Python reads like English
  • Suitable for learning from Kids to Elderly People.
  • It's having a larger community, so more likely you'd get help if you ask questions
  • The more useful projects there are, the more likely someone has already built a function you need.
  • On Angel List, Python is amongst top demanded and the highest average salary offered skill.

What Python is not?

  • Python is not compiled level language, Hence it is slow compared to C++ or C.
  • Python can't be used in the development of real time action and feedback systems.
  • Hence, Operating systems like Windows, Linux does not use python for the developmwent but C, C++.
  • Its not hardware oriented language. You can't run python programs for controlling hardware without any interface.
  • Due to duck typing and dynamic typing (please Google it) leads to runtime errors.

Terminology:

  • High Level: Any human who can read and understand spoken language.
  • Interpreter: Translates one statement at a time rather than whole source code file. Hence, slower in execution.
  • Scripting: Work can be done by giving commands of platform like OS, DBMS.
