What is Python3
“Python3” (Python 3) is an open source programming language. It is used in various fields such as web development, artificial intelligence development, and data analysis.
The feature of Python3 is that you can write programs concisely.It uses simple syntax, so even programming beginners can use it.
Another feature is that there are many “libraries”. A collection of programs useful for development is called a “library”.
4 fields where Python3 is used
Python3 is used in various fields.This is because you can easily create the desired program using a rich library.
One of the fields where it is used is web application development and site construction. Applications such as YouTube and Instagram are also developed with Python3.
It is also used in the development of cutting-edge fields. Python3 is a programming language that can be used in all fields.
Utilized field 1: IoT
IoT is an abbreviation for “Internet of Things”. A system that allows home appliances to communicate via the Internet.
Python3 is a web-friendly language.You can develop a system that controls devices that connect to the Internet.
As a specific example, it is possible to acquire and accumulate data from surveillance camera systems. You can also create functions that let you know about what your camera sees.
Utilized area 2: Web application development
Python3 is a language suitable for developing web applications. I would say that almost anything you can do in other programming languages is possible in Python3.
Web application development is the creation of services such as website construction and SNS bulletin boards.You can also use other frameworks together for more efficient development.
One application that uses Python3 is YouTube. The reason is that it operates at high speed and can be maintained by a small number of people.
Utilized area 3: AI development
Various functions are necessary for the development of AI (artificial intelligence). Python3, with its rich library and frameworks, meets this criteria.
Python3 code is very simple and easy to read. Code written by others can be easily read.This means that it is an easy-to-use language for AI developers who don’t specialize in programming.It can be said that even programming beginners can use it.
Utilized area 4: Analysis tools and data analysis
Python evolved in the field of scientific computing. Libraries that specialize in computation have also been developed and are popular for their ease of use.
Libraries are also needed to collect, process and visualize data.Python3 has a rich library, so data analysis can be done easily.
Python3 is also effective for automating complicated Excel operations. Once you create a program, you will be able to perform various data processing.
