I have downloaded the 64-bit version for my 64-bit Windows 10.
After completing the download, double click the installer to start the installation. The welcome screen shows the default installation location and provides options to Install the launcher for all users and to add Python 3.9 to the system path as shown in Fig 3.
After checking the checkboxes for Launcher and System Path, I have clicked the Customize installation Link to choose the installation components and to change the installation path. It shows the components including Documentation, pip, tcl/tk and IDLE, Python test suite, py launcher, for all users as shown in Fig 4.
Click the Next Button to choose Advanced Options as shown in Fig 5.

Step 3 - Verify Installation
In this step, we will verify the installation of Python. Search for Python on system tray as shown in Fig 8. It will show all the available options.
Now execute the Python command-line option as highlighted in Fig 8. It will start the Python command line window as shown in Fig 9.
It shows that Python 3.9.0 is installed as part of this tutorial. We can also verify the version on Windows Command Prompt as shown in Fig 10.
This is how we can verify the installation of Python 3 on Windows 10.
In this step, we will write our first program in Python to print Hello Python on the console.
Open any editor of your choice and write the basic program as shown below.
# Print Hello Python
print( "Hello Python" )
Now save the file. I have saved it as hello.py. We can simply execute it using the python command as shown in Fig 11.
In this tutorial, we have installed the most recent version of Python 3 i.e. Python 3.9.0 on Windows 10, and also executed our first program to print Hello Python on the console.
