[Python] Chapter 01-01 About Python (First Python)

[01-01] Python for the first time

Before we get started with Python programming, let's get a quick overview.

Here, we will look at what you can do by learning Python and explain the main features of the Python language.

Also, since the Spring 2nd Reiwa exam, Python can be selected for programming the afternoon exam of the Fundamental Information Technology Engineer Examination (FE), so I would like to explain it to those who are thinking of choosing Python. ..

Programming language

Many of you may be familiar with programming languages, but there are various programming languages such as C, Java, C #, C ++, JavaScript, and PHP. This time, we will deal with a programming language called Python.

Features of Python

Compared to other languages, the Python language has the following main features.

――Simple grammar ――Easy to learn even for beginners in programming ――Can be used in various OS environments ――Can run on Linux as well as Windows --Since it is distributed as open source (*) </ font>, you can use it freely.

(*) </ font> The idea is that the source code written in the programming language can be opened to the public and anyone in the world can freely modify it.

Usage of Python

Roughly speaking, Python can do various things (*) </ font>, and as mentioned above, it is used for various purposes because of its simple grammar.

--AI (artificial intelligence)

  • IoT --Data analysis --Data science

(*) </ font> Python has many functions called "libraries", which allow you to do various things.

Python3 "3" is the version. From now on, the Python version will be explained in 3. Originally Python was divided into ** Python2 ** and ** Python3 **.

However, the programs written in Python2 cannot be run in Python3, and the libraries have come to support Python3, and now most of them are Python3.

Finally

That's a brief overview of Python. From the next time onward, I will actually write a Python program, execute it, check its operation, and explain the installation of the development environment.
