This article will explain in detail the example analysis of the operation principle of the pdb module in python. The editor thinks it is very practical, so I share it with you for reference. I hope you can get something after reading this article.
1. Pdb module is not a built-in module implemented by c, but a module implemented and packaged by pure Python.
Pdb.py is the core file, which inherits the bdb and cmd modules.
2. Define and realize the interactive input of a series of debugging commands by using cmd module, and track the stack frame of the code based on sys.settrace insertion.
Control the operation and breakpoint status of the code according to different debugging commands, and output the corresponding information to the console.
Example
Import pdbdef combine (S1 ~ S2): # define subroutine combine, which... S 3 = S1 + S2 + S1 # sandwiches S2 between copies of S1,... S3 ='"+ S3 +'" # encloses it in double quotes,... Return S3 # and returns it.a = "aaa" pdb.set_trace () b = "bbb" c = "ccc" final = combine (AForce b) print final on the "example analysis of the operation principle of the pdb module in python" this article shares here, I hope the above content can be of some help to you, so that you can learn more knowledge, if you think the article is good, please share it out for more people to see.
