Getting Started in Coding with Python for Beginners (Part 1)

 

Maybe you have just browsed the internet, social media, or talked with Siri on your iPhone, and suddenly a question popped up in your mind, “How do they create all of these?” Well, the answer is Data Science. You have probably known the answer and looked for more technical answers on how exactly someone does data science. Then, you will stumble upon Python, the most popular data science tool (a programming language, to be specific) to date. But, how to get started? That is why you googled up and decided to open this article.

There are numerous ways to get your Python ready to go. However, my favorite one is using Jupyter Notebook as the Integrated Development Environment (IDE). What is IDE, you asked? Just think of it as your workshop where you write your code and showcase what can your code do. You can write your code without IDE, but it will be more difficult. IDEs provide you with all the tools you need, check your syntax, and analyze what goes wrong on your code.

Jupyter Notebook is not the only IDE. There are many other IDEs out there, such as VS Code, Pycharm, Programiz, Idle, etc. However, as a Jupyter user, I will guide you on how to use Jupyter Notebook to write your Python code. In my opinion, Jupyter is powerful enough for my coding needs and it is faster than any other IDEs.

I divided this guidance into three parts: install Anaconda Python in your machine, working with Jupyter Notebook, and finally showing some basic syntaxes in Python. Okay, let’s get started!

Install Anaconda Python

To install, open your web browser and go to anaconda.com. Click “Get Started” on the top right.

Choose “Download Anaconda installers”.

Click “Download”, or choose according to your operating system under “Get Additional Installers”, and wait until the download is done.

Once it is complete, you should just need to click the installer, and proceed through a standard installation process.

At some point in the installation, it will ask whether you want to install Pycharm. However, we should skip this step as we have agreed to use Jupyter Notebook as our IDE.

After the installation is complete, you now can write some Python codes! To do so, open your terminal (on OS X) or command (on Windows), and type “python”.

Press return or enter, then you should receive what version of python that you have in your machine. As you can see below, mine is 3.9.7. Yours might be newer than mine.

Now, let’s try do the hello world tradition by typing: print(“Hello, world”).

There you go! You are now officially writing your first Python code!

To exit from the Anaconda, type exit().

Okay, that is it for this article. Next, I will show you how to work on Jupyter Notebook. See you in the next article and I hope you enjoyed my article. Best of luck!

Joe Biden Versus The Developing World: The Effect of Global Minimum Tax to The Third World's Investment Attractiveness

Image
The US has aggressively proposed the enactment of worldwide minimum tax for corporations in the last months. In the early of July, Joe Biden was able to get 130 countries around the world to set a minimum tax rate of 15 percent that all companies pay, which is known as Global Minimum Tax (GMT). For the US, GMT is a tool to stop multinational enterprises from shifting their money from US to countries with lower tax rates. The Organization for Economic Cooperation and Development (OECD) estimated the GMT would generate extra $150 billion of tax revenue for the US each year. GMT is a scheme to reduce tax competition between countries which is expected to reduce tax avoidance of multinational enterprises. When it is implemented, the home country would be able to charge income tax at the GMT's rate when the corporation's effective tax rate is lower than the GMT rate. Effective tax rate is different with statutory tax rate, which can be seen in the domestic tax regulations. Effective...

Getting Started in Coding with Python for Beginners (Part 3)

  This part covers basic syntaxes in the Python programming language using Jupyter Notebook. However, you can also use another Integrated Development Environment (IDE), such as Pycharm, VS Code, Idle, or any other IDE. The syntaxes are still the same no matter what IDE you are using. If you are looking to install Python or navigate Jupyter Notebook, you should check my previous articles   here   and   here . Basically, all programming languages can be divided into sequential, branching, and looping. We will discuss the basic syntaxes in Python from there. Sequential Sequential programming is when our code consists of operations one over the other, which will be run in a sequence, just like counting from 1 to 10. Sequential is the basic logic on how computers run our instructions. Computers always execute our code in order, unless you tell them otherwise, from the very top to the very bottom. For example, let’s make our previous “hello world” code to take the user’s n...

Tes TOEFL ITP (ETS certified) di STAIN (IAIN) Palopo

Image
Tugas negara pada tahun 2017 membawa saya untuk menjejakkan kaki dan tinggal cukup lama di kota Palopo, sebuah kotamadya di Sulawesi Selatan. Meskipun sebuah kotamadya, jangan bayangkan bila kota ini memiliki fasilitas yang lengkap layaknya kota-kota di Jawa, terlebih dari segi pendidikan. Itu sebabnya pada awalnya saya pesimis dapat menemukan tempat tes TOEFL bersertifikat internasional di kota ini. Sejak awal tiba disini, saya sudah bersiap untuk menempuh perjalanan sejauh kurang-lebih 360km ke Makassar untuk mendapatkan TOEFL Certificate . Tapi ternyata saya salah. Salah satu perguruan tinggi negeri di kota Palopo ternyata mengadakan TOEFL Institutional Testing Program (ITP) bersertifikat Educational Testing Service (ETS). Bahkan menurut informasi yang saya peroleh, hanya ada dua kota di Sulawesi Selatan yang memiliki perguruan tinggi ataupun provider TOEFL-test yang bersertifikat ETS, yaitu Makassar dan Palopo. Perguruan Tinggi Negeri (PTN) tersebut adalah Sekolah Tinggi Aga...
