Language features of python:
1, simple
Python is a language that represents simple ideas. Reading a good Python program is just like reading English. It enables users to focus on solving problems rather than understanding the language itself.
2, easy to learn
Python is very easy to use because its documentation is very simple. Easy to read and maintain: clear and unified style, forced indentation.
3. Faster speed
The bottom layer of Python is written in C language, and many standard libraries and third-party libraries are also written in C, which runs very fast.
4. Free and open source
Python is a kind of FLOSS (free/open source software). Users can freely distribute copies of the software, read its source code, modify it, and use some of it in the new free software. FLOSS is based on the concept that a group shares knowledge.
