description of all the modules in the standard library.Use the source codeFor those who want to really understand the Python language. To understand the module, can not be separated from the source code. Reading the source code is actually the best way to learn python--in addition to writing your own. Real reading is not a problem, but the problem is the source. Suppose you want to read the source code f

series of callback functions, which is a recurring pattern in the Erlang system.Further readingIn this section we focus on the similarities between twisted and Erlang, but they are a lot different. One of the unique features of Erlang is the way it handles errors. A large Erlang program is structured as a tree-structured process group, with "regulators" on the upper level and "workers" on the leaves. If a worker process crashes, the regulatory process will notice and act accordingly ( Usually r

This article mainly introduces the class and object learning tutorials in Python object-oriented programming. object-oriented is the basic feature of Python, the features and usage of classes and objects are the basic skills in Python learning. if you need them, you can refe

displays and makes it possible to has several code files side-by-side on larger displays. Use blank lines to separate functions and classes, and larger blocks of code inside functions. When possible, put comments on a line of their own. Use Docstrings. Use spaces around operators and after commas, but not directly inside bracketing constructs: a = f (1, 2) c5>+ g (3, 4). Name your classes and functions consistently; The Convention is to use CamelCase for classes and Lower_case_with_un

Pyenv python$ pyenv versionsInstallation python version$ pyenv install The installed version will be in the ~/.pyenv/versions directory.For larger version files, such as Anaconda, can be downloaded first to the official website, and then put the file in the ~/.pyenv/cache directory, and then execute the installation command, PYENV will not repeat the download.In addition, you can use --list the parameters

use a backslash to escape the backslash itself. Such as:But when the string inside itself with a lot of backslashes, it is very troublesome. The second workaround is to use the original string notation.The original string starts with R and can put any character in the string, and the only requirement is that the last character is not allowed to be a backslash. If the only requirement is met, you can assume that any character in a string is part of the string itself.21. Unicode string:is not the

self and why you don't need to assign a value to it. Give an example to make this clearClear Suppose you have a class called MyClass and an instance of this class MyObject. When you call this object's methodMyobject.method (Arg1, arg2), this is automatically converted from Python to Myclass.method (MyObject, Arg1,ARG2)-This is the principle of self.This also means that if you have a method that does not require parameters, you still have to define a

in fact it is not a tuple, is the number 1(1) tuple functionlist () functions similar to listswhen you use the tuple function, you can split the string and list into tuples. (2) Creating tuplesuse the tuple () function to createEnumeration Creation(3) accessing tuples and tuple shardsTuples are also tuples after they are fragmented. (4) In general, you can use lists instead of tuples when you do not change the content itself. However, in two cases, tuples are irreplaceable. ① tuples can be used

object is called a tamper-unpickling from a string expression. Objects in the encapsulated state can be stored in files or objects, or transferred between remote machines over a network.If you have an object x, a file object F that opens in write mode, the simplest way to encapsulate an object is just one line of code:Pickle.dump (x, F)If f is a file object opened in read mode, you can reload the object:x = Pickle.load (f)(If you don't want to write the encapsulated data to a file, there are so

is a measure of the distance between each point in a cluster and the points in an adjacent cluster.Analyze Contour FractionsThe score range is [-1，1] . The following is an analysis of this score- A score of 1 points-close to +1 points indicates that the sample is far from the neighboring cluster. A score of 0 points-a score of 0 indicates that the decision boundary between a sample and two adjacent clusters is or is very close. A score of-1 points-a negative score indicates tha
