How can I see a table of the local variables?

[mooffie]

I want to see all the local variables and their values, in a compact way (e.g., if I have a huge array, I want the display trimmed to one line (so I can't use locals()).).

DeepSeek tells me to type whos, but ipdb replies with NameError: name 'whos' is not defined.

I don't think there is a command that fits those constraints exactly. You can write one yourself and define an alias:

ipdb> help alias
      Usage: alias [name [command]]

      Create an alias called 'name' that executes 'command'.  The
      command must *not* be enclosed in quotes.  Replaceable
      parameters can be indicated by %1, %2, and so on, while %* is
      replaced by all the parameters.  If no command is given, the
      current alias for name is shown. If no name is given, all
      aliases are listed.

      Aliases may be nested and can contain anything that can be
      legally typed at the pdb prompt.  Note!  You *can* override
      internal pdb commands with aliases!  Those internal commands
      are then hidden until the alias is removed.  Aliasing is
      recursively applied to the first word of the command line; all
      other words in the line are left alone.

      As an example, here are two useful aliases (especially when
      placed in the .pdbrc file):

      # Print instance variables (usage "pi classInst")
      alias pi for k in %1.__dict__.keys(): print("%1.",k,"=",%1.__dict__[k])
      # Print instance variables in self
      alias ps pi self

If you do, consider sharing!
