Python is a High-Level Programming Language. It is also one of the most popular programming languages in the world. Because of its simplicity and efficiency, we can use Python to make everyday work easier.

Developed by Dutch programmer Guido van Rossum, the programming language was first released in 1991. It was called Python Version 0.9.0. Then in 2000 Python 2.0 was released. Then, with the rise of Python 2.7, Python 3 was introduced. Currently (April 2021) Python 3.9.4 Stable release has been released.

We look forward to continuing the Python tutorial.

Essential Post-Installation Steps on Windows

Once you have finished running the Python installer, follow these critical verification steps to ensure your Windows command line is configured properly:

  1. Verify Python and Pip in Command Prompt:

    Open Windows Terminal or CMD and run the following commands to confirm your installation version:

    python --version
pip --version
  2. Fix 'python is not recognized' Error:

    If Windows outputs that 'python is not recognized', the executable was not added to your system environment variables. Open System Properties > Environment Variables, find Path under User variables, and add the installation path (usually C:\Users\<YourUsername>\AppData\Local\Programs\Python\Python3x and its Scripts directory).

  3. Setting Up a Virtual Environment (venv):

    Always create isolated environments for your coding projects to avoid package version conflicts:

    python -m venv myenv
myenv\Scripts\activate

Frequently Asked Questions

Q: Should I install Python from python.org or the Microsoft Store?
A: We strongly recommend downloading the installer directly from the official python.org website, as it gives you full control over custom installation paths, pip integration, and environment variables.
