Its goal is to provide all the niceties of modern GUI-based debuggers in amore lightweight and keyboard-friendly package. PuDB allows you to debug coderight where you write and test it--in a terminal.

Here are some screenshots:

• Light theme

  

• Dark theme

  

You may watch screencasts too:

• Meet Pudb, a debugger for Python code (2020)
• PuDB Intro Screencast (2009)

• Syntax-highlighted source, the stack, breakpoints and variables are allvisible at once and continuously updated. This helps you be more aware ofwhat's going on in your program. Variable displays can be expanded, collapsedand have various customization options.
• Pre-bundled themes, including dark themes via "Ctrl-P". Could set a custom theme also.
• Simple, keyboard-based navigation using single keystrokes makes debuggingquick and easy. PuDB understands cursor-keys and Vi shortcuts for navigation.Other keys are inspired by the corresponding pdb commands.
• Use search to find relevant source code, or use "m" to invoke the modulebrowser that shows loaded modules, lets you load new ones and reload existingones.
• Breakpoints can be set just by pointing at a source line and hitting "b" andthen edited visually in the breakpoints window. Or hit "t" to run to the lineunder the cursor.
• Drop to a Python shell in the current environment by pressing "!".Or open a command prompt alongside the source-code via "Ctrl-X".
• PuDB places special emphasis on exception handling. A post-mortem mode makesit easy to retrace a crashing program's last steps.
• Ability to control the debugger from a separate terminal.
• IPython integration (seewiki)
• Should work with Python 3.6 and newer. (Versions 2019.2 and older continueto support Python 2.7.)
