2. Scripting language . Write a script anywhere and anytime to process data , It is very convenient .
3. Rich library .Python In dealing with various areas of the class library is also very rich , Reptiles 、 machine learning 、 Data processing 、 Image processing and so on meet the needs of most fields .
Python The main disadvantage of is the slow running speed , and C The program is very slow , because Python It's interpreted language , Your code will be translated line by line into CPU Understandable machine code , This translation process is very time-consuming , So it's slow . and C The program is compiled directly into CPU Executable machine code , So very fast .
What are interpreted languages and compiled languages ：
Python Powerful , Can be used to do Web Development 、 Automatic operation and maintenance 、 Data analysis 、 Game development 、 automated testing 、 machine learning 、 Reptiles 、 Development of embedded and desktop applications, etc .
