It also supports post- mortem . As a programmer, one of the first things that you need for serious program development is a debugger. In software development, debugging is the process of looking for and resolving issues that prevent computer software from running correctly. In this tutorial, we will go ove.
It includes features to let you pause your program, look at the values of variables, and watch program execution step-by-step, so you can understand what your program actually does and find bugs in the logic. It will also include some helpful tricks to make your debugging sessions a lot less stressful.

I am the first script in this demo ( Pdb ). At this point you can either set breakpoints or continue executing your program.
Another special thing about . It is an interactive debugger that you can start up anywhere in your codebase. Python interactive shell. This makes debugging complex or confusing code much simpler, since you can interact directly with the code in a running state. Reading_large_PDB_files import sys import Bio.
What you use it for is to create you own custom shell. Output capture in other tests is not affected. Any prior test output that has already been captured and will be processed as such.
Any later output produced within . Two speed improvements for those who spend their time in python the pdb ( python debugger) or the zopectl debugger. It supports setting (conditional) breakpoints and single stepping at the source line level, inspection of stack frames, source code listing, and evaluation of . Hamelryck T(1), Manderick B.

Editor , press Fto run winpdb on the currently edited script). I typically would like to inspect the stack at the point of error to figure out the cause of it.
