Use the PDB library debugging program in Python and the pythonpdb library debugging The pdb library that comes with Python finds that it is very convenient to use pdb to debug the program. Of course, pdb cannot be used for remote debugging or multithreading. There are multip

recent work has not made any progress, I can only say ExtJS a little bit big, hard to chew ~ In Python, it is often possible to move from one object to another to facilitate subsequent computations, which can be implemented using copies. Generally speaking, the copy is divided into three kinds: 1. pointer reference, 2. Shallow copy, 3. Deep copy. One, pointer reference Objects in Python are assigned

A powerful library:Turn from: Public numberOne of the best places in Python is a large number of third-party libraries, with a wide range of amazing coverage. One drawback of the Python library is that the global installation is done by default. In order for each project to have a separate environment, you need to use the tool virtualenv, and then work with the P

Today I found a very interesting feature, Python comes with a document viewer for all libraries, configured as follows:To configure the Pydoc service, enter the following code in CMD:python –m pydoc –p 1234After the carriage return, the window is not closed during use.Then, enter the URL in the browser: http://localhost:1234/, open the Python's own and integrated third-party library API.The interface looks

When it comes to concurrency, we think of multithreading and multi-process.Does it use multiple processes or multithreading? It depends on the situation. Our procedures are generally divided into:1) consume the network (a large part of the time is in the network interaction);2) CPU consumption (full use of multicore)In the first case, most of the time is occupied by the network delay, so the use of multithreading and multi-process are similar.In the second case, the length of time is determined

What Virtualenv is. Virtualenv is a tool to create isolated Python environments. In order to isolate different versions of the development environment (if the project is collaborative development, the version of the library problem is a headache, with this can be in their own environment to run). Step one, install Virtualenv: (PIP installation refer to Python thi

Python third-party library installation method summary, python Installation Method Python is an elegant language with simple syntax and powerful functions. Of course, a wide range of third-party libraries can accelerate development. So the question is, how to install these third-party libraries (packages? There are not

We often deal with files and directories, and for these operations Python provides an OS module that contains many functions for manipulating files and directories. To know what the methods are, we can run the following statement to output all of the OS module information on the screen:Import oshelp (OS)If you understand Linux basic operations, some of the following OS methods should be familiar, because the basic and Linux operating methods are the s
