A programming language
Programming language: a language developers to communicate with the computer. When it comes to programming languages I have to mention programming. Programming will develop their logical thinking in order to be able to identify the computer code files.
1.1 Classification of programming languages
Programming language developed historically divided into three categories: machine language, assembly language and high-level language
1) machine language
The first generation programming language, was born in the early computer, the language used. Machine language advantage is that the highest efficiency, but the development efficiency is low, learning is very difficult.
Machine language
2) assembly language
On the basis of the machine language, assembly language developed. Assembly language than machine language, the assembly language sacrifice a little efficiency, but the development efficiency, reduce the learning curve.
Assembly language
3) high-level language
Assembly language is still developing relatively low efficiency, high-level language is the language appears that the situation has improved. High-level language with respect to machine language and assembly language in terms of high-level language stand in the perspective of developers, and machine language associated with assembly language and hardware more closely, standing in computer hardware design point of view. Therefore, the development of high efficiency high-level language, reducing the learning curve is low, but low efficiency.
High-level language can also be divided compiled and interpreted. Compiled common language is C, only compiled after the program is completed, view the compilation was successful. Interpreted languages such as python, every write will immediately result.
Python interpreter and two mounting pycharm
