Important Python Terminologies that Students & Beginners Must Know

Tangerang – Python, is one of the high-level programming languages ​​and is most widely used in Data Science. As a popular programming language, Python has many libraries or modules and is supported by a large community.

Presenting the theme “Python for Data Professional Beginner,” Daniel, in a Live Session with DQLab, last Tuesday, September 13, 2022, conveyed several advantages of the Python programming language. First, it is open-sourced or can be accessed by everyone freely and for free. Second, the use of Python is flexible enough to run many jobs. Third, Python is a high-level programming language that is easy for humans to write and read.

In dealing with this programming language, there are three important terms that students and beginners must know. The three terms are variables, statements, and comments. Before explaining the three terms, Daniel emphasized that beginners should learn Python step by step with the most basic things, including these three terms.

Variables are places that are used to store values ​​repeatedly by programs. This allows us to hold data or information so that many data can be called simultaneously in a variable. Even so, Daniel explained, there are some rules that need to be known in variables.

“In this variable, the rule is that the name of the variable must start with a letter (a-z, A-Z), or it can also be an underscore character (_), but cannot start with a number (0-9),” Daniel said.

The second term important for students and beginners is “statement.” Statements are commands that are given, written, and executed line by line by the program. Statements are essential to know because they will be written in all types of coding. You can use the print() command to display statements in Python. According to Daniel, Python has privileges in using this statement.

“Well, one thing that makes Python different from other programming languages is the use of a semicolon (;). In Python, we don’t need to end the code written with the semicolon,” Daniel said.

After variables and statements, Comments are the basic Python terms that are mandatory for beginners to know. Comments in Python are a collection of written text that will not affect the result. It is used to mark the coding that has been made.

“With comments, it will be easier for us to remember and understand the coding made. Comments in Python can be made in the form of a single line or multiple lines,” Daniel said.

Any data-related work will work closely with programming languages, including Python. Python can help data practitioners complete various jobs, from cleaning data, performing statistical analysis, and using Machine Learning to making applications.

Python is an indispensable programming language in the Data Science field. Non-IT students don’t need to worry, practice competence, and hone Python skills from the basics, so it’s easier with DQLab.
