I have a generic class that launch an interactive session:

class SomeClass(object):
    def interact(self):
        from IPython import embed
        embed()

and a script which use that class:

from test_ipython_class import SomeClass

global WANTED

WANTED=1234

def someFunc():
    o=SomeClass()
    o.interact()

someFunc()

My problem is that in the interactive session I cannot access the global variable WANTED:

PS C:\Temp\test_ipython> ls

The question is "how to get access to globals like 'WANTED' while keeping 'SomeClass' generic, i.e. not hardcoding explicitly all globals."

  • You are trying to access a global variable of different file? If so, try reading this: https://stackoverflow.com/questions/3400525/global-variable-from-a-different-file-python – Amiram Apr 05 '20 at 13:28
  • Thanks for the pointer but my aim is different: I am trying to have a generic class "SomeClass" which encapsulate IPython.embed() AND which offer to the user access to globals from his file (as well as locals of the scope which invoked "SomeClass.interact()". – acapola Apr 07 '20 at 22:02
