built in 1949. In that encoding model, each binary digit, or bit, is encoded low then high, or high then low, for equal time. Also known asphase encoding, the Manchester process of encoding is used in consumer infrared protocols,radio frequency identificationandnear-field communication...
In cryptography, a plaintext message is converted to ciphertext using a combination of numerical computations that appear incomprehensible to the untrained eye. Techniques like mathematical concepts and algorithms are used to make the transferred data difficult for others to decode. In other words, the...
Accessing string value in Python programming language is easy to do, and can be an invaluable tool when working on larger programming projects. Python has a built-in setup for accessing the characters in each string, known as 'slicing'. With the slicing syntax, anyone can “extract” or “...
This article explains the new features in Python 3.0, compared to 2.6. Python 3.0, also known as “Python 3000” or “Py3K”, is the first ever intentionally backwards incompatible Python release. There are more changes than in a typical release, and more that are important for all Python ...
The app knows this data represent a Unicode string encoded with UTF-8 and must show this as text to the user. First step, is to convert the binary data to numbers. The app uses the UTF-8 algorithm to decode the data. In this case, the decoder returns this: ...
“In video editing and production, video encoding is the process of preparing the video for output, where the digital video is encoded to meet proper formats and specifications for recording and playback through the use of video encoder software.” ...

facilitating communication between two or more nodes over a network. Web browsing is an example of socket programming. The user requests the web server for information, and the server processes the request and provides the data. In Python, for creating a simple socket, the socket library is ...
Back in 1997 Ramon Neco and Mikel Forcada suggested the “encoder-decoder” structure for machine translations, which became popular after 2016. Imagine translation is a text-to-text procedure, where you need techniques to first encode the input sentence to vector space, and then decode it to ...
What's new in Python3 更详细的介绍请参见python3.0的文档 Common Stumbling Blocks 本段简单的列出容易使人出错的变动。 print语句被print()函数取代了,可以使用关键字参数来替代老的print特殊语法。例如: Old:print"The answer is", 2*2 New:print("The answer is", 2*2)...
