open the Python console program, suggested tickFifth, the fifth Precompile standard library is a precompiled public library, this feature is not very clear, but almost all of the pre-compilation purpose is to improve the subsequent running speed bar, the disadvantage is that it will cause additional disk overhead, and will slow down the installation speed, If yo
features usually aren ' t very sophisticated. On Unix, whoever installed the interpreter could have an enabled support for the GNU ReadLine Library, which adds more Elaborat e Interactive editing and history features. Perhaps the quickest check to see whether command line editing are supported are typing control-p to the first Python prompt You get. If It beeps, you are command line editing; See Appendix
its API is difficult to use. (Project address: Https://github.com/shogun-toolbox/shogun)2, KerasKeras is a high-level neural network API that provides a Python deep learning library. For any beginner, this is the best choice for machine learning because it provides a simpler way to express neural networks than other l
list object. Because this list object is shared with other objects (referenced by other objects), a change like this will not only affect T1. It is important to realize that as such modifications, it affects the rest of the program.If you do not want this to happen, Python is required to copy the object instead of creating a reference. Methods include the built-in list function and the copy module of the standard

Summary: Good writing, support comprehensive, good tune, speed is not slow.
1.
Python is the language of interpretation, which makes it easier to write a program. For example, in a compiler language such as C, write a matrix multiplication, you need to allocate the operand (matrix) of memory, allocate
1 Advantages of PythonThe Python language library is complete, simple in syntax, and has its own installation on Linux, with unique features in handling big data and automation.2 Python InterpreterThe Python interpreter is used to interpret Python code, and the more popular
About Python
Python is an object-oriented, interpreted computer programming language. Python syntax concise and clear, with rich and powerful class library and many other features, this is from the introduction of Baidu Encyclopedia, in the Baidu Encyclopedia can also see its more detailed introduction information

I. Usage of threads in Python:
In Python, there are two ways to use threads: functions or classes to wrap thread objects.
1. Functional Method: Call start_new_thread () function in the thread module to generate a new t
Programming language Classification Method 1:
Compile type: such as c,c++, write code as source file, to edit build executable file to execute
Interpreted type: Like VBS, Python does not need to compile, use the interpreter to execute, better executable; Java uses a compromise between the two, compiling the generated file is still dependent on the interpreter execution, so it belongs to the explanatory language
Programming language C
and optimize execution speed through various optimization methods. On the other hand, in "real life" (meaning the foreground, human interface, etc.), Python speed is fast enough, plus now the CPU processing speed, enough to exceed people's response speed. In addition, even in the field of real-time computing, it is necessary to adopt a separate architecture-real-time processing of parts and support, which can be used to connect the entire system thro

6. Python is no more than three, operation and maintenance/devops,web development, data analysis/algorithm. Each has a corresponding library, you are gradually familiar with their usage, even you push XX in the production environment, the effect is very good, mood gray often good.
7. As you use more and more deep, you need to master more
find a relevant job, it is easy to get into the road. Some graduate students engaged in machine learning and scientific computing will encounter many difficulties when they directly go to the python third-party library to write code, it is recommended to supplement basic knowledge.
Whether you can write code to solve the problem is to determine whether you have
