Starting the Programming Journey

Writing the Hello World Program using Python on Colab

Starting the Programming Journey

Let us begin our common programming journey by deciding on the programming language that we will use and the IDE.
For our journey we will use Python and our IDE will be Colab.

Here is some information about the Python programming language.Python documentation.

Why do we choose Python?

1. It is free and it is free source.

2. Python has an extensive, robust and well documented library, and what is more it increases per day.
   Python Libraries can be searched here.
   PyPi

3. The Python Syntax and terms mirror natural languages. For instance and, or, not remain and, or and not and do not become &&,|| and !. Python doesn’t use {} for blocks. That is done by indentation. The same applies to other parts of Python as well.

4. Python is interpreted and can be run statement by statement. This is very handy and is used extensively in making interactive applications.

5. Python is Object Oriented and has functions. Every language has this.

6. Python is dynamically typed.

7. Python can be downloaded from its official site.

8. We will not be downloading Python because we will do our programming on Colab. What is Colab?
   I quote from the Colab site
   ”Colaboratory, or Colab for short, is a product from Google Research. Colab allows anybody to write and execute arbitrary python code through the browser, and is especially well suited to machine learning, data analysis and education. More technically, Colab is a hosted Jupyter notebook service that requires no setup to use, while providing access free of charge to computing resources including GPUs.”

9. Running a program on Colab.
   Steps

   1. Goto this link Colab Research

      

      
      

   2. New Notebook

      

   3. Start writing code

      

   4. Code written.

      

   5. Press the play/run button.
      Wait for the animation to end.
      

      

   6. Check the output.

      

   7. Change the name to helloworld.pynb

      

      
      

   8. Press save

      

      .

   9. Here is a link to the saved file helloworld.pynb.
