Python Python and characteristics of
1.Python is a programming language, it's just one of many programming languages
2. The syntax is simple, elegant, easy to read programs written in.
3. Cross-platform that can run on Windows, Linux and MacOS
4. easy to learn.
the extremely powerful and rich standard library and third-party libraries, such as e-mail, such as graphical GUI interface
6.Python is object-oriented language (thought)
So many languages, why I like Python
1. Introduction, elegant, flexible, philosophy
2. easy to use difficult to master

Basic grammar
basic grammar of any language is the basis of only the master can flexibly use language to write efficient, beautiful
clean code
Pythonic
Python syntax is very flexible and unique learning language must learn its style, characteristics, this is the language of
the essence .Python especially true
Python performance and optimize the
data structure is the basis
Too many frameworks, libraries too much, too much technology. Let us return to the nature of language and enjoy the sheer beauty of the language itself
