Following are the installation steps.

1: First, download the official Python latest version for windows from the following link Download the latest version of Python for Windows. Otherwise you can also select the version that you want to install and download.

For example, I had downloaded Python 3.8.5 Windows Installer which is suitable for my project.

If you are starting project from the scratch, I would recommend you to download latest stable version of Python.

2: Run the Executable Windows Installer. After the installation wizard is launched, make sure that you select the following checkboxes.

  • Install launcher for all users (recommended) checkbox.
  • Add Python 3.8 to PATH checkbox.

3: Afterwards, select Install Now in the launched setup wizard.

4: Once the installation is completed, you would see message “Setup was successful

5: Verify the Python installed on Windows 10 and environment variables are correctly setup.

Open the command prompt and check the value of PATH variable.

C:\Users990>echo %PATH%

C:\Windows\system32;C:\Windows;C:\Windows\System32\Wbem;C:\Windows\System32\WindowsPowerShell\v1.0\;
C:\Users990\AppData\Local\Programs\Python\Python38-32\Scripts\;C:\Users990\AppData\Local\Programs\Python\Python38-32\;

Check Python version installed on Windows

C:\Users990>python

Python 3.8.5 (tags/v3.8.5:580fbb0, Jul 20 2020, 15:43:08) [MSC v.1926 32 bit (Intel)] on win32
Type "help", "copyright", "credits" or "license" for more information.

Check/ Verify pip installed – Part of Python Installation on Windows

Note, for all recent versions of Python the recommended installation options include pip i.e., most latest distributions of Python comes with pip pre-installed. Python 3.4 and later versions include pip by default.

pip is the package-management system written in Python. This tool is used to install and manage software packages for Python. pip is called the Python Package Index.

Verify whether pip is pre-installed by running the following command in the cmd prompt.

> pip --version

pip 20.1.1 from c:\users990\appdata\local\programs\python\python38-32\lib\site-packages\pip (python 3.8)

Install Jupyter Notebook – Python 3

Also, note that Jupyter Notebook is not installed/included by default with Python. Therefore, you need to install jupyter notebook.

Jupyter Notebook is open-source software that provides easy-to-use interactive data science environment across many programming languages like Python.

Check if jupyter notebook is installed.

> python -m notebook

C:\Users990\AppData\Local\Programs\Python\Python38-32\python.exe: No module named notebook

From the above error it is understood that jupyter is not installed on your windows machine.

Therefore, you can to install Jupyter on Windows 10 using the following pip install command if you wanted to explore this feature too.

> pip install jupyter
