Python- Using the IDLE to run your program

  1. Start up the IDLE. Then under File, select New Window or prss CTRL + N, which will open up an untitled window. This is where we will be writing our first program.python12
  2.  In the untitled window, write your first programpython13
  3. Give the file a name and save it (hello.py in this case)
  4. Next, under Run, select Run Module
  5. Now in the main window (IDLE SHELL), you will see the output as shown below:python15
  6. The SHELL is restarted every time one runs a module in IDLE. We can now proceed to writing full length programs!

Python- Setting the PATH

So, after installation of python, we need to update the environment variable PATH in windows 10.

  1. Click Windows + Pause, to start the System Properties and update the value for PATH as shown below:

    2. Start your command prompt and type : PATH. This should now include the installation directory of Python.

The Start

So I have decided to learn two new languages in 2017, beginning 11th April 2017 . For quite a while I wanted to learn Python and ADF and this blog marks the beginning of the journey.

The first post was to install Python and write the Hello World program. I will write new posts as I learn more about these two languages.

 

Python- The Firsts

  1. Installing Python :  Visit https://www.python.org/   and click on Downloads–>Windows. python1
  2. Download the executale. Here I have downloaded python-3.5.2  python2.PNGpython3.PNG
  3. Once the executable is downloaded (python-3.5.2-amd64.exe), double click on the file which will lauch the setup.

     

  4. Once this is done, navigate to C:\Users\<yourusername>\AppData\Roaming\Microsoft\Windows\Start Menu\Programs\Python 3.5, you should see the following :python6
  5.  Click on the IDLE (Python 3.5.64-bit) and the python shell is launched. python7.PNG
  6. And thats it! Takes less than 5 minutes to install python.
  7. Okey, Finish it up with the customary Hello World program. (The error to show that the parentheses are required from python 3 and above. Print has moved from being just a “statement” to being a “function”!)python8
