absrtact : When writing Python scripts, if we use Python to process Web page data or work with Chinese characters, this error message often occurs: syntaxerror:non-ascii character ' \ Xe6 ' in file./filename.py of Line 3, but no encoding declared. This article focuses on issues related to Unicode and Chinese, and special character encoding in Python. What rules should be followed for character encoding and decoding.

ASCII: The United States Standard Information Interchange code, is now the most common single-byte encoding system. Here is a simple understanding of what the code means. Coding is the process by which information transforms from one form or format to another. A conversion convention is required in this process. When all the data in the computer is stored and run, all the information is represented by the binary number (0,1), and what binary data repr

Currently, the most widely used character set and Its Encoding in computers are American Standard Code for information interchange (American Standard Code for information interchange) developed by the National Bureau of Standards (ANSI ), it has been set as an international standard by the International Organization for Standardization (ISO), known as the ISO 646 standard. It is applicable to all Latin characters, including 7-digit ASCII code and 8-di
ASCII, American Standard Code for Information Interchange reads like "astkey" and defines the English letters or the same result and meaning represented by the 127 numbers ranging from 0 to one hundred and twenty-eight. Because only seven digits (bit) can be used to represent numbers from 0 to 127, most computers use eight digits to access the character set (character set ), therefore, numbers between 128 and 255 can be used to represent another group
ASCII (American Standard Code for information interchange) is a computer coding system based on Latin letters. It is mainly used to display modern English and other Western European languages. It is the most common single-byte encoding system today and is equivalent to the international standard ISO/IEC 646.

The so-called ASCII and 16 binary are just conceptual things that are all binary in the computerThe conversion should be the output of the conversion, the same number, in the computer memory is the same, but the output is not the sameASCII is the encoding of characters, almost the encoding of characters on the keyboard.

Files in a computer can be divided into two types: ASCII files and binary files.
An ASCII file is also called a text file. It is defined as a file containing ASCII characters. It is usually created by a text editor similar to NotePad. Similarly, binary files are defined as files with binary information, which are usually generated by certain programs such as com
