Help (Won’t you please help me if you can)¶
help [command [subcommand]|*expression*]
Without argument, print the list of available debugger commands.
When an argument is given, it is first checked to see if it is command name.
If the argument is an expression or object name, you get the same help that you would get inside a Python shell running the built-in help() command.
If the environment variable $PAGER is defined, the file is piped through that command. You’ll notice this only for long help output.
Some commands like info, set, and show can accept an additional subcommand to give help just about that particular subcommand. For example help info line give help about the info line command.
