Running the Python command line.<\/p><\/div>\n

If you want to run a Python script and you don’t have Python on your system already, fear not. There are a number of options available to install Python, covering a wide variety of different platforms.<\/p>\n

How to Install Python: From python.o<\/strong><\/span>rg<\/strong><\/span><\/h3>\n

Probably the easiest way to install Python is to go to the official Python site’s download page (http:\/\/www.python.org\/downloads\/). Select the release version you want to download, and select the appropriate operating system. The source is also available as a gzipped tarball. If you are running Linux, you may already have Python installed. Ubuntu, for example, includes Python by default. If not, you should be able to install Python from the repositories by typing:<\/p>\n

sudo apt-get install python<\/strong><\/p>\n

When prompted, type the superuser password, and installation will begin.<\/p>\n

IDLE, the official Python GUI.<\/p><\/div>\n

Once Python is installed, you should be able to invoke the Python interpreter at the command line by typing “python<\/strong>“. Alternatively, you can create a shortcut for Python on your desktop and click on the icon. Clicking on “pythonw<\/strong>” should start IDLE, the Python GUI. You may, however, have problems running IDLE on certain versions of Windows. I myself could not start pythonw under Windows 8.1. If you have the same problem, you might consider using an alternative method for starting IDLE:<\/p>\n

    \n
  1. Start the Python command line. You can do this [1] by launching a command prompt and typing “python<\/strong>“; [2] by double-clicking “python.exe<\/strong>” in the File Explorer; [3] by right-mouse clicking on the Windows logo in the lower left corner of the desktop, selecting “Run<\/strong>” and launching python.exe from “Run<\/strong>“, or [4] creating a desktop icon for Python and clicking on it.<\/li>\n
  2. In the Python interpreter, type “import idlelib.idle<\/strong>” and press <ENTER><\/strong>. IDLE should now launch.<\/li>\n<\/ol>\n

    Whether you are using the basic Python command interpreter or IDLE, you can start typing in Python code. Typing and executing the Python Hello World program is almost trivial:<\/p>\n

    >>> print(‘Hello, world!’)<\/strong>
    \n Hello, world!<\/strong><\/p>\n

    As you can see, the Python interpreter runs the program without the need to compile the code, one of the advantages of using Python. Using IDLE provides the following advantages over the standard Python shell:<\/p>\n
