Expected

Brings up a docs page for the object passed in

Help on dict object:

class dict(object)
 |  dict() -> new empty dictionary
 |  dict(mapping) -> new dictionary initialized from a mapping object's
 |      (key, value) pairs
 |  dict(iterable) -> new dictionary initialized as if via:
 |      d = {}
 |      for k, v in iterable:
 |          d[k] = v
 |  dict(**kwargs) -> new dictionary initialized with the name=value pairs
 |      in the keyword argument list.  For example:  dict(one=1, two=2)
 |  
 |  Methods defined here:
 |  
 |  __contains__(self, key, /)
 |      True if the dictionary has the specified key, else False.
 |  
 |  __delitem__(self, key, /)
 |      Delete self[key].
 |  
 |  __eq__(self, value, /)
 |      Return self==value.

This is added by the site module on startup (which we have), we just aren't able to import pydoc yet so it doesn't work.

So the challenge becomes to import pydoc?

[coolreader18]

Yep!

It seems that this works now, and that the issue can be closed!
