Yes, indeed, it is important to stress that enough logging is essential to the application. You should keep track of important things, and if your records are good enough, you can save a lot of time by identifying problems from the logs.

Idle is an integrated development environment that comes with the python software package. It allows beginners to easily create, run, test, and debug Python programs. This article describes the idle GUI, Python shell, editor, and debugger in detail, helping beginners get started quickly.

This article mainly introduces how to use the pdb module to debug Python program instances. This article focuses on pdb. run () function, pdb. runeval () function, pdb. runcall () function, pdb. the use of set_trace () functions and pdb debugging commands can be found by the Python interpreter, however, logic errors or variable usage errors are not easy to find.
This article mainly introduces how to use VIM + XDebug to debug the PHP program on the server. although there are many articles about how to use Eclipse + XDebug to Debug PHP on the developer's work machine, however, VIM + XDebug is rarely configured in the system, and an old plug-in is used in current articles on VIM settings. Here we mainly introduce a new plug-in DBGPavim, which has many advantages over
Everyone knows that Python is a built-in Pdb library, and it is very convenient to debug Python programs using Pdb. However, Pdb cannot be used for remote debugging and multithreading. let's take a look at how to debug Python and common commands using the Pdb library. Everyo
Python Debug single-step debugging, pythondebugI have been worried about python debugging. I used to compile c and debug it directly with gdb, Which is easy and pleasant. I don't know what to do if I encounter such an interpreted program. Using log is sometimes a small program, and you don't want to write so much code.

This is a small note.The code used to write in Python is not complex with external dependencies, which are debugged locally and run without problems, and can be put into production to run. However, a recent project, due to the use of some internal services, needs to be connected to the internal environment for debugging.If you change the code every time, publish it to your on-premises environment to run your tests, and the process is a little cumberso
Debug runs anytime, anywhere. Note that the Vscode default after debugging, will stop in the first sentence, such as.

Python Linux debugging
Python is a dynamic language, and the compiler does not check the runtime syntax. These low-level problems often result in low debugging efficiency. Previously, debugging on Linux servers was done through print and error reporting. Python's built-in PDB is a powerful tool for debugging.
Let's create a new test Script: shell code.

Python 2.6 New multiprocessing, that is, multi-process, to the sub-process code debugging a bit difficult, such as Python's own PDB if you start directly in the child Process code will throw a bunch of exceptions, because the child process stdin/out/ Err and other files are closed and PDB cannot be called. Reportedly winpdb, Wing IDE Debugger can support such remote debugging, but seems to be too heavy (well the former is much lighter than the latter,
