HOW TO USE PYTHON, ITS USES AND APPLICATIONS

Are you a programmer? Or are you planning to learn to program? Or are you searching for the best programming language to start with? And that is the reason why you decided to program. If so, then please be assured first. That you have made the best decision to start with Python. Python is one of the foundation languages that every programmer should know. And its language is used in many other coding languages. If you have mastered Python, then you won’t be struggling that hard to learn other coding languages. But hey, before we tell you “how to use python?”. The first thing you should know is “what is python?”

WHAT IS PYTHON?

Python is a high-level general-purpose programming language that is interpreted. The use of substantial indentation in its design philosophy promotes code readability. Its language features and object-oriented approach are designed to assist programmers in writing concise, logical code for small and large-scale applications.

USE OF PYTHON.

In this era of mobiles, laptops, Bluetooth, and gadgets. You will find programming languages everywhere, especially Python. A few of the examples you wish to know are Dropbox, Youtube, Instagram, Pinterest, Disqus, Spotify, Dropbox, Uber, and Reddit. These are just a few big names, there are many more popular sites and applications that you use daily, and which run on Python’s coding.

WHY YOU SHOULD USE PYTHON.

This question doesn’t have a specific answer. There are a handful of reasons for you to use Python. We have listed the top most popular reasons below.

  • FREE OF COST. Python is an absolutely free programming language to use. That can be used for both personal and business reasons.
  • IT’S FREE AND OPEN SOURCE. Python development is something that everyone and anyone can do.
  • ACCESSIBLE. Python is a coding language that has no age boundaries. It has been learned by people of all ages, from high school students to old age retirees, and obviously, you can too.
  • VERSATILE. As already discussed, Python has numerous purposes to be served for. It is useful for a variety of different tasks, which include, GUI development, scripting, data research, web development, and more.
  • POWERFUL. Small scripts can be written to automate monotonous activities. Python may also be used to build complicated and large-scale corporate applications.

HOW TO USE PYTHON?

If you want to get it done without even struggling a bit. We would suggest you run it through Thonny IDE.

The newest version of Python is included in the Thonny IDE. As a result, you will not need to install Python individually.

We have simplified it for you. You can go through the below steps, and follow them to run Python on your computer/ laptop.

i) Start with downloading Thonny IDE.

ii) To install Thonny on your PC, run the installation.

iii) Navigate to File > New. After that, save the file as a “.py” file. For instance, “pranchal.py,” “prajjwal.py,” and so on.

You may name the file whatever you like. Make sure the filename should end with “.py.”

iv) Fill up the file with Python code and save it.

v) Then select Run > Run current script or just press F5.

If you don’t want to download it using Thonny. You can download it directly too. Here’s how.

i) Get the most recent Python version.

ii) Run the installer and follow the on-screen instructions to install Python.

Check the box to add Python to environment variables during the installation process. Python will be added to the environment variables, and you will be able to run it from wherever on the machine.

NOW START USING PYTHON.

i) RUN PYTHON IN IMMEDIATE MODE.

Python is now installed. Invoke the interpreter in immediate mode by entering “python” in the command line. To retrieve the output, we can simply write in Python code and click Enter.

Try entering “1 + 1” and pressing the enter key. As a result, we obtain the value “2.” You may use this prompt as a calculator. Type quit() and press enter to exit this mode.

ii) RUN PYTHON IN THE INTEGRATED DEVELOPMENT ENVIRONMENT (IDE).

To write a script file, you can use any text editing software.

All we have to do now is save it as a “.py” file. Using an IDE, on the other hand, may make our lives much easier. An integrated development environment (IDE) is a piece of software that gives beneficial features to programmers for application development, such as code hinting, syntax highlighting and checking, file explorers, and so on.

Also know that, when you are installing Python, an IDE known as IDLE will get downloaded along with it. That can also be used to run Python on the computer itself. It is one of the finest IDE if you are a beginner.

At the time, when you launch IDLE, it launches an interactive Python Shell with it.

You may now make a new file with the “.py” extension and save it. For instance, “pranchal.py.”

Fill up the file with Python code and save it. To launch the file, select Run > Run Module from the menu bar, or just press F5.

START YOUR FIRST PYTHON PROGRAM.

Now that you are done downloading Python, and setting its functions. You can finally start writing your first Python Program.

Let’s start by making a very basic program named Hello World. A “Pretty Easy” program is a basic program that displays the phrase “Pretty Easy!” on the screen. Because it’s such a basic program, it’s frequently used to teach novices a new programming language.

Now type “print(“Pretty Easy”) in any text editing software or an IDE. And after that save it as “Pretty_Easy.py”

After that, execute the file. The output will be shown on the screen as “Pretty Easy”.

And see that is how you just wrote your first program in Python.

And we are sure that with our guidance it seemed pretty easy right. That is how you learn “Python Programming language”.
