Py3 101: Getting started with python3.


Python is an interpreted high-level general-purpose programming language. Its design philosophy emphasizes code readability with its use of significant indentation. Its language constructs as well as its object-oriented approach aim to help programmers write clear, logical code for small and large-scale projects.

Why python.

  • It is very simple to use and implement.
  • It is open source and has a very big community of developers.
  • Object-oriented and functional programming.
  • A lot of applications.

Installing python.

The installation procedure involves downloading the official Python .exe installer and running it on your system.
The version you need depends on what you want to do in Python.
Open your web browser and navigate to the Downloads for Windows section of the official Python website.

For all recent versions of Python, the recommended installation options include Pip and IDLE. Older versions might not include such additional features.
The next dialog will prompt you to select whether to Disable path length limit. Choosing this option will allow Python to bypass the 260-character MAX_PATH limit. Effectively, it will enable Python to use long path names.

Pip is a powerful package management system for Python software packages. Thus, make sure that you have it installed.

To verify whether Pip was installed:

Open the Start menu and type "cmd."
Select the Command Prompt application.
Enter pip -V in the console. If Pip was installed successfully, you should see the following output:
