We will learn how to write python code and running it using Python.It is mandatory to install Python in our computer in order to excecute python programs in our machine, however you can use any online python compiler in platforms such as onlinegdb. We will first learn how to install Python Software in windows operating system then proceed further with python code excecution.

Installng Python for windows operating system.

  2. Select install for all users as well as Add Python 3.9 to path checkboxes.
  3. Click Install Now as shown below. Install Now
  4. The installation progress bar will appear as shown below. Setup Installation Progress

When the Python setup installation is done, we can see a Setup was successful message as shown below. Setup was Successful 5. Click the close button.

Testing Python Installation in Window 10.

  1. Click the start button on the task bar of the Windows 10 OS. Since all applications are displayed in alphabetical order, scroll down to P and view Python 3.9 folder, inside this folder you’ll see icons named:

Add a dot at the end of the directory and click OK. (.) Dot represents where Python gets executed. Therefore the dot will enable Python to run on any directory.

Different ways of executing a Python Program.

There are mainly three ways of exucting Python programs.

  1. Python command line.
  2. Python IDLE.
  3. Using system prompt.

Python command line and Python IDLE are generally termed as interactive modes because the PVM executes the code immediately after a programmer types one line at a time. System prompt is also referred as non-interactive mode since the PVM has to execute the whole code after being written by a programmer.

Using Python’s command line.

click on your windows start button then search for Python
