About this site
At Python101.tech, we learn the basics of Python. The content is designed to enable you to write basic Python code in the shortest time possible. This course is systematically structured and ideal for those who want to start programming but are unsure where to begin. Terms unfamiliar to beginners are explained with illustrations to promote deeper understanding.

In addition to articles on writing programs, there are also articles on setting up a Python execution environment and using text editors.
Even experts
This site is designed to help even experienced users quickly look up Python code when they forget how to write it. (Of course, it's also for my use.)
What is Python in the first place?
Python is a programming language that is increasingly used in the fields of AI and Machine Learning. It is also used in Robotic Process Automation, a field that focuses on enhancing the efficiency of administrative tasks.
RPA(Robotic Process Automation)
RPA is a technology that automates routine tasks performed by people on computers, and contributes mainly to improving efficiency and productivity in back-office operations.
In September 2024, it will become possible to use Python in Excel, enabling the replacement of existing administrative tasks with Python.
By using Python, it becomes easier to create code with complex conditional branching (where tasks are divided and processed based on conditions), and tasks that previously had to be performed manually one by one can now be processed instantly by Python.
The programming language Python
Python is one of the most accessible programming languages.
For example, if you want to display the text “Hello, World!”, the difference between Python and other languages is as follows. (In this example, we will use C++ as another programming language.)
【Python】
print('Hello, World!')
【C++】
#include <iostream>
int main() {
std::cout << "Hello, World!" << std::endl;
return 0;
}
In Python, simply enter the text you want to display inside the parentheses following the function name “print” (functions will be explained in a separate lecture). The word ‘print’ means “to display or output text on the monitor,” so it is easy to remember.
On the other hand, in the C++ programming language, various types of code that resemble magic spells are added, and these must be written for the program to run correctly. Even for the line that outputs text (line 4), commands such as “std::cout” and “std::endl” must be written.
In this way, Python is characterized by its ability to write code that is concise and easy to understand.
Finally
Even a long journey begins with a single step. Let's take it one step at a time and move steadily toward our goal together!
