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

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

The following issues were found in Python today:1. After the from matplotlib import Pyplot as PLT, then import cv2Cv2.imshow () is not working, and I don't know why.My workaround now is to use CV2 to read the image and then call Plt.imshow () to display the image without using cv2.imshow () to display the imageThe color space in the CV2 Library of 2.OpenCV is arranged differently from the color space in the

Use the mock library in Python to simulate and test the Python code. How to test without patience Usually, the software we write interacts directly with services that we call "dirty. In layman's terms, services are crucial to our applications, and the interaction between them is well designed, but this will bring us undesirable side effects-those features that
