This article mainly introduces the relevant knowledge of Python basic knowledge case analysis, the content is detailed and easy to understand, the operation is simple and fast, and it has a certain reference value. I believe you will gain something after reading this Python basic knowledge case analysis article. Let's take a look at it.

1. In Python, objects are passed by reference.

2. Multivariate assignment is actually tuple assignment

3. Write the module

4. Always remember a fact

5. Dynamic type

6. Variables are tracked and managed in memory through reference counting

7. Exception handling

8. All Python objects have three features

9. Boolean value

10. Object identity comparison

11. Cmp ()

12. Str () and repr ()

13. Isinstance () and type (), which mainly reflect the optimization of the code

14. Classification of standard types

15. Operations between different data types

16. Python division:

17. Factory function

18. Built-in function

(1) built-in functions for all data types:
