- ZMQInteractiveShell.ast_transformers : List
- Default: [] - A list of ast.NodeTransformer subclass instances, which will be applied to user input before code is run. 
- ZMQInteractiveShell.autocall : 0|1|2
- Default: 0 - Make IPython automatically call any callable object even if you didn’t type explicit parentheses. For example, ‘str 43’ becomes ‘str(43)’ automatically. The value can be ‘0’ to disable the feature, ‘1’ for ‘smart’ autocall, where it is not applied if there are no more arguments on the line, and ‘2’ for ‘full’ autocall, where all callable objects are automatically called (even if no arguments are present). 
- ZMQInteractiveShell.automagic : CBool
- Default: True - Enable magic commands to be called without the leading %. 
- ZMQInteractiveShell.cache_size : Integer
- Default: 1000 - Set the size of the output cache. The default is 1000, you can change it permanently in your config file. Setting it to 0 completely disables the caching system, and the minimum value accepted is 20 (if you provide a value less than 20, it is reset to 0 and a warning is issued). This limit is defined because otherwise you’ll spend more time re-flushing a too small cache than working 
- ZMQInteractiveShell.color_info : CBool
- Default: True - Use colors for displaying information about objects. Because this information is passed through a pager (like ‘less’), and some pagers get confused with color codes, this capability can be turned off. 
- ZMQInteractiveShell.colors : ‘NoColor’|’LightBG’|’Linux’
- Default: ‘LightBG’ - Set the color scheme (NoColor, Linux, or LightBG). 
- ZMQInteractiveShell.debug : CBool
- Default: False - No description 
- ZMQInteractiveShell.deep_reload : CBool
- Default: False - Enable deep (recursive) reloading by default. IPython can use the deep_reload module which reloads changes in modules recursively (it replaces the reload() function, so you don’t need to change anything to use it). deep_reload() forces a full reload of modules whose code may have changed, which the default reload() function does not. When deep_reload is off, IPython will use the normal reload(), but deep_reload will still be available as dreload(). 
- ZMQInteractiveShell.disable_failing_post_execute : CBool
- Default: False - Don’t call post-execute functions that have failed in the past. 
- ZMQInteractiveShell.history_length : Integer
- Default: 10000 - No description

- ZMQInteractiveShell.prompts_pad_left : CBool
- Default: True - Deprecated, use PromptManager.justify 
- ZMQInteractiveShell.quiet : CBool
- Default: False - No description 
- ZMQInteractiveShell.readline_parse_and_bind : List
- Default: [‘tab: complete’, ‘”\C-l”: clear-screen’, ‘set show-all-if-a... - No description 
- ZMQInteractiveShell.readline_remove_delims : Unicode

- Default: False - Debug output in the Session

- Session.item_threshold : Integer
- Default: 64 - The maximum number of items for a container to be introspected for custom serialization. Containers larger than this are pickled outright.
