How python sets the file encoding: 1. Use "coding=
"; 2. Use "-*- coding: -*-" 3. Use the "vim: set fileencoding= :" method to set.
If you want to fill in Chinese characters in a file in python2, you must add a line of code to declare the file encoding comment, otherwise python2 will report an error. Because its default encoding format is ASCII. This problem no longer exists in python3. The default file encoding of python3 is UTF-8. Today I will introduce how to set file encoding in python, which has a certain reference effect. I hope it will be helpful to everyone
[Recommended course: Python tutorial]
To put the coding comment on the first or second line, generally speaking, the first two lines of the Python file should be written like this:
#!/usr/bin/python # -*- coding: UTF-8 -*-
The first line specifies the python interpreter, and the second line specifies the python interpreter. The second line specifies the python file encoding method. There are the following optional methods to set the encoding method
(1) Use the setting method with an equal sign
#!/usr/bin/python # coding=<编码名称>
(2) Use the setting method with colon, which is the method that most editors can correctly identify
#!/usr/bin/python # -*- coding: <编码名称> -*-
(3) vim form method
#!/usr/bin/python # vim: set fileencoding=<编码名称> :
Setting the encoding statement of the header has the following functions:
1. If there are Chinese comments in the code, this statement is needed
2. More advanced editors will The Ministry declares this as the format for code files.
3. The program will be initialized through header declaration and decoding, so the storage format of the header declaration and the code must be consistent
Summary: The above is the entire content of this article, I hope it will be helpful to everyone Helps.

Python is suitable for data science, web development and automation tasks, while C is suitable for system programming, game development and embedded systems. Python is known for its simplicity and powerful ecosystem, while C is known for its high performance and underlying control capabilities.

You can learn basic programming concepts and skills of Python within 2 hours. 1. Learn variables and data types, 2. Master control flow (conditional statements and loops), 3. Understand the definition and use of functions, 4. Quickly get started with Python programming through simple examples and code snippets.

Python excels in gaming and GUI development. 1) Game development uses Pygame, providing drawing, audio and other functions, which are suitable for creating 2D games. 2) GUI development can choose Tkinter or PyQt. Tkinter is simple and easy to use, PyQt has rich functions and is suitable for professional development.

Python is easier to learn and use, while C is more powerful but complex. 1. Python syntax is concise and suitable for beginners. Dynamic typing and automatic memory management make it easy to use, but may cause runtime errors. 2.C provides low-level control and advanced features, suitable for high-performance applications, but has a high learning threshold and requires manual memory and type safety management.

To maximize the efficiency of learning Python in a limited time, you can use Python's datetime, time, and schedule modules. 1. The datetime module is used to record and plan learning time. 2. The time module helps to set study and rest time. 3. The schedule module automatically arranges weekly learning tasks.

Python is better than C in development efficiency, but C is higher in execution performance. 1. Python's concise syntax and rich libraries improve development efficiency. 2.C's compilation-type characteristics and hardware control improve execution performance. When making a choice, you need to weigh the development speed and execution efficiency based on project needs.

Python excels in automation, scripting, and task management. 1) Automation: File backup is realized through standard libraries such as os and shutil. 2) Script writing: Use the psutil library to monitor system resources. 3) Task management: Use the schedule library to schedule tasks. Python's ease of use and rich library support makes it the preferred tool in these areas.

Is it enough to learn Python for two hours a day? It depends on your goals and learning methods. 1) Develop a clear learning plan, 2) Select appropriate learning resources and methods, 3) Practice and review and consolidate hands-on practice and review and consolidate, and you can gradually master the basic knowledge and advanced functions of Python during this period.
