INTRODUCTION TO PYTHON








                 PYTHON
                 Python is a popular high-level programming language. It is a powerful language used for
                 general-purpose programming. Python was developed by Guido van Rossum. He started
                 applying Python in 1989. Python is extensively used to develop:

                    games                                               websites
                    Graphical User Interface programs                   web applications


                 INSTALLING PYTHON

                 Follow these steps to download and install the Python software:

                 Step 1:   Open the website http://www.python.org/downloads.

                 Step 2:   Click on the Download Python 3.12.1 button.

                 Step 3:    Double-click on the downloaded software. You can either look at the bottom of the
                          screen or locate the  software in  the  Downloads folder  of  your  computer. The
                          Security Warning dialog box appears.

                 Step 4:   Click on Run button. The Python Setup window appears.

                 Step 5:   Select the Add python.exe to PATH checkbox.

                 Step 6:   Click on Install Now button.

                 After a few seconds, Python will be successfully installed on your computer.

                 PROGRAMMING IN PYTHON

                 Python has two basic programming modes—Script Mode and
                 Interactive Mode.

                 Working in Interactive Mode

                 Interactive Mode is a command line shell which gives immediate
                 result  for  each  command. In  Interactive  mode,  we  type  one
                 command at a time. Python executes the given command and

                 gives the output.
                 Follow these steps to start Python and work in Interactive Mode:


                 Step 1:   Click on Start button.                                              Opening Python
