We know that the encoding method should be declared in the header file of Python source code. If you don't just use ASCII code, many people may write a little different: # Coding = UTF-8 # Coding: UTF-8 #-*-Coding: UTF-8 -*- So how can we effectively write data? What advantages are ineffective? For more info
Summary of python coding best practices and python coding Best Practices I believe that many of you have used python, and I have always had a special liking for python. There is no doubt that as an interpreted Dynamic Language,
Python coding (14) and python CodingI. Knowledge of character encoding 1. How the text editor accesses files (nodepad ++, pycharm, word) Open the editor and start a process, which is in the memory. Therefore, the content written in the editor is also stored in the memory. After power failure, data is lost and therefore needs to be saved to the hard disk, click th
byte is set to 0, and the next 7 bits are the Unicode code for the symbol. so for the English alphabet, the UTF-8 encoding and ASCII code are the same. 2) for n-byte notation (n>1), the first n bits are set to 1, the n+1 bit is set to 0, and the first two bits of the subsequent bytes are set to 10. The rest of the bits are not mentioned, all of which are Unicode codes for this symbol.Now: ASCII encoding is 1 bytes, and Unicode encoding is usually 2 bytes, Utf-8 is one of the implementations of
about the historical evolution of the code, UTF-8 is how to develop, why Windows still keep GBK encoding ... And so on, online a search a lot of, most of them are forwarded, share after the same content, still can not solve my inner doubts ... Coding is a matter of egg pain, if not clear, how to mix in China? I have set a basic world view of coding by looking through multiple documents and in-depth
To summarize, you can handle Unicode characters from the python1.6 start. one, several common coding formats.1.1, ASCII, expressed in 1 bytes. 1.2, UTF-8, with 1 to three bytes, representing ASCII code for only 1 bytes, ASCII encoding is a subset of UTF-8. 1.3, UTF-16, in 2 bytes, in Python, the meaning of Unicode is UTF-16. Second, the Python source file encod
Python file Header TemplateLet's start with a little bit of knowledge: How to automatically add file header information when creating a file !By: File--settings each time through the file--setings to open the settings page too troublesome! You can select the toolbar toolbar by: view--The modified effect:The first line of the Python Script templateThis is very simple to tell the system with what explanation
Unicode characters can be processed as a generalization, starting with python1.6. one, several common coding formats.1.1, ASCII, expressed in 1 bytes. 1.2, UTF-8, expressed in 1 to three bytes, the ASCII code occupies only 1 bytes, ASCII encoding is a subset of UTF-8. 1.3, UTF-16, expressed in 2 bytes, in Python, the meaning of Unicode is UTF-16. Second, the Python
Decided to start the Python road, using spare time, for more in-depth study of Python. Programming languages are not art, but work or tools, so it is necessary to organize and follow a set of coding specifications. So this afternoon I made a copy according to Pep 8, and I'll follow this code, and I'll keep updating it.PEP8 Py
Summary of coding knowledge in python, python Encoding Problem During normal work, I encountered the following error: UnicodeDecodeError: 'ascii' codec can't decode byte It is common that everyone has encountered it. So I decided to organize and learn python encoding. Basic knowledge In python2.x, there are two data ty
: Universal code, a standard encoding, Python2 the encoding that is used by default. At least 16 bits are required to store. Other encodings are optimized for this encoding, such as UTF-8,GBK.UTF-8: Compression and refinement of Unicode (numbers, letters and ASCII codes using 8-bit encoding to store), Python3 default encoding used, European characters: 2 bytes, 16-bit storage; Chinese characters: 3 bytes, 24 bit storage Summary: Python3 default encoding is UTF-8, encoding conversion principle:

Strings are the most commonly used data types in Python, and many times you use characters that do not belong to the standard ASCII character set, and the code is likely to throw Unicodedecodeerror: ' ASCII ' codec can ' t decode byte 0xc4 In position 10:ordinal not in range (128) exception. This anomaly is easy to come across in Python, especially in python2.x, a problem that puzzles beginners. However, if
