Serious missing features of both pdb and ipdb compared to GDB:
PYTHON SCRIPT DEBUG MODE HOW TO
Python -m module debugging has been asked at: How to debug a Python module run with python -m from the command line? and since Python 3.7 can be done with: python -m pdb -m my_module Or alternatively, as in raw pdb 3.2+ you can set some breakpoints from the command line: ipdb3 -c 'b 12' -c 'b myfunc' ~/test/a.pyĪlthough -c c is broken for some reason: I don't know how to set the context size there without hacking ipdb.you would have to go through all function and class definitions as Python reads those lines.Then removing it is easy with dd since everything is contained in a single line.Ĭontext=21 increases the number of context lines as explained at: How can I make ipdb show more lines of context while debugging?Īlternatively, you can also debug programs from the start with: ipdb3 main.pyīut you generally don't want to do that because: So I can type just ipd and it expands to the breakpoint. You likely want to add a shortcut for that from your editor, e.g.
PYTHON SCRIPT DEBUG MODE INSTALL
Usage is analogous to pdb, just install it with: python3 -m pip install -user ipdbĪnd then add to the line you want to step debug from: _import_('ipdb').set_trace(context=21) Much like pdg, ipdb is still far from perfect and completely rudimentary if compared to GDB, but it is already a huge improvement over pdb. Ipdb adds IPython functionality to pdb, offering the following HUGE improvements: Note: All these commands should be execute from pdb Stepping into subroutines… with “s” (step into)Ĭontinuing… but just to the end of the current subroutine… with “r” (return) Turning off the (Pdb) prompt… with “c” (continue) Printing the value of variables… with “p” (print) Repeating the last debugging command… with ENTER Step-by-Step debugging to go into more internalĮxecute the next statement… with “n” (next) Type "help", "copyright", "credits" or "license" for more information.įor a big project and long-running module, can start the debugging from inside the program using While developing early versions of modules and to experiment it more iteratively. Most straight forward way, running from command line, of python interpreter $ python -m pdb scriptName.py By using Python Interactive Debugger 'pdb'#įirst step is to make the Python interpreter to enter into the debugging mode.
