Pdb Python Cheat Sheet

Python has a PDB and PHP counterpart is XDebug. Both the debugging tools provide you with standard features like stacks, breakpoints, path mapping, and so on. For this reason, it is hard to decide on which language is better in terms of debuggers. R2 -b 32 -d rarun2 program=pwn1 arg1=$(ragg2 -P 300 -r): runs pwn1 with a De Bruijn Pattern as first argument, inside radare2's debugger, and force 32 bits r2 -d rarun2 program=/bin/ls stdin=$(python exploit.py): runs /bin/ls with the output of exploit.py directed to stdin.

IPython / Jupyter¶

• Using IPython makes interactive work easy.
  • Better shell
  • Notebook interface
  • Embeddable kernel
  • Parallel python

IPython shell shortcuts¶

• TAB expansion to complete python names and file paths
• ~ and * directory / file expansion
• many 'magic' methods:

Run¶

To run a program directly from the IPython console:

%run has special flags for timing the execution of your scripts (-t) or for running them under the control of either Python's pdb debugger (-d) or profiler (-p):

Other Commands¶

• %reset is not a kernel restart
• Restart with Ctrl+. in 'qtconsole'
• import module ; reload(module) to reload a module from disk

• Start with: ipython notebook and switch to browser
• Keyboard shortcuts:
  • Enter to edit a cell
  • Shift + Enter to evaluate
  • Ctrl + m or Esc for the 'command mode'
