Learn a new technique or language, we must first learn how to adapt to this new technology, which in the adaptation process, we have to learn how to debug the program and play the corresponding log information, is called "as long as the log is good, no bugs can not solve", in our well-known information technology, The Log4xxx series, as well as the Android.util.Log packages for Android apps, are all for developers to get a better log information servi

Now I'm in the Debug Python program just simply print it out in the wrong place, and don't know if Python has a single-step debugging tool like some C + + ides? Or how does the Python God debug his own

two pipelines are only associated with the terminal window you are working on , so when a program prints out the output, you can see the output, and when a program crashes, you can see the debug information. (If you are working on a Windows-based Python IDE system, stdout and stderr default to "interactive Windows.") ）‘‘‘2b.

This is an overview of the tools I used for debugging or analysis, not necessarily complete and comprehensive, if you know better tools, please mark in the comments. Log 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. If you have ever used the print statement to

In the previous article we learned why Python is debugging, and the two methods of Python debugging, but the debugging method is not finished, so in this article we will talk about the remaining two debugging methods. Hopefully, these kinds of debugging methods will help you get on the path to learning python faster. Logging The third method is: replacing
