I discovered that there are 3 default namespaces ->

https://github.com/ipython/ipython/blob/79921f6fe380f57cf353d76615e4fd8472c83118/IPython/core/interactiveshell.py#L1405

But you could somehow change or add other namespaces (maybe ipdb could
add local namespace to evaluate local variables).

You could check thist code:

import IPython
ip = IPython.core.getipython.get_ipython()
print(ip.user_ns)  # this is in 'Interactive' namespace
print(ip.user_global_ns)# this is in 'Interactive (global)' namespace

# next line show how somewhat somewhere could change namespace where
object names are searched
ip._inspect("pinfo", "None", [("my namespace", {"None":None})])

iPython ? magic

[Steve D'Aprano]

In the iPython interactive interpreter, obj? prints information about the given
object. For example:


In [11]: None?
Type:   NoneType
Base Class: 
String Form:None
Namespace:  Python builtin
Docstring:  


Does anyone know that the Namespace field is supposed to show? I can't get it to
display anything except either "Python builtin" or "Interactive".

“Cheer up,” they said, “things could be worse.” So I cheered up, and sure
enough, things got worse.
