A Quick Response code(QRCode) is a two-dimensional pictographic code used for its fast readability and comparatively large storage capacity. The code consists of black modules arranged in a square pattern on a white background. The information encoded can be made up of any kind of data (e.g., binary, alphanumeric, or Kanji symbols).
Streaming is the technique for transferring data at fixed rate in real time between the client and the server. There are many streaming protocols available for streaming data. HTTP, RTSP, MMS, RTMP, RTP, MSB, MBSD, RTCP etc. are the streaming protocols.
Audio format is a file format for storing the digital audio data on a computer. The encoding of the audio data is done by the encoder according to the file format specifications.The data in the file may be in compressed or uncompressed format.
The audio format is categorized into three types:
1. Uncompressed audio Format:
2. Lossless Compression:
3. Lossy Compression:
Audio Quality is the accuracy and enjoyability of the audio which the user can listen from an electronic device. Audio quality depends upon the bit rate, sample rate, file format and encoded method. It also depends on the ability of the encoder to get the important bits right.
Python descriptors are object attributes that are only invoked for new style of classes. Python descriptors comes under the category of meta programming(code that manipulates code). The descriptors are accessed with special classes that allows to: -- manage properties of another class and -- implement an interface for get, set and delete We can also say that the descriptors are object attributes and the attribute access is overridden by one of the methods in descriptor protocol.
When something goes wrong with your code instead of using standard debugging techniques such as print statements use debugging tools. I found two great tools for debugging.
1. using the code module.
2. pdb module.
Writing good code is a habit that comes from mixing several approaches and changing practices by learning from your own experiences. And mostly its about thinking pessimistic. There is no happy programmer because there are infinity ways to break your code, all you need to look for is to cover all the pit falls by following best practices.
Python is an interpreted, object-oriented, high-level programming language with dynamic semantics. Python's simple, easy to learn syntax emphasizes readability and therefore reduces the cost of program maintenance. During execution the Python source code is translated into bytecode which is then interpreted by the Python interpreter. Python source code can also run on the Java Virtual Machine, in this case you are using Jython.
