i.e. can you do something like:

if we_are_in_ipython:
    do_some_ipython_specific_stuff()

normal_python_stuff()

I guess what I'm trying to do is very loosely along the lines of #if DEBUG in C# (i.e. using ipython as a debugging tool and command line python to run the code without the debugging stuff in there).

    Isn't IPython mainly intended for interactive use? Then you probably know that you are using it. –  Feb 01 '12 at 09:35

  • Ok maybe a concrete example will help. If I'm using ipython, I put the line `from IPython.Debugger import Tracer; debug_here = Tracer()` at the top of my file and then `debug_here()` statements throughout the file. However the first line generates an error from the command line (`AttributeError: 'function' object has no attribute 'colors'`) and additionally I wouldn't want the `debug_here()` statements to be called anyway – tdc Feb 01 '12 at 09:38

  • @user647772 If you want to write a library that supports additional functionality when in IPython/Jupyter, you need a way to case that off. – Kyle Kelley Oct 19 '16 at 19:22

Check for the __IPYTHON__ variable:

def is_ipython():
    try:
        __IPYTHON__ 
        return True
    except: 
        return False

  • What if I have `__IPYTHON__` as a variable – Jakob Bowyer Feb 01 '12 at 11:03

    Python uses `__name__` with leading and trailing underscores for special system functions with pre-defined behaviour. It would be a bad nomenclature from programmers part is what i feel. – avasal Feb 01 '12 at 11:19

As explained on the duplicate, you can use the try/except method, or

if '__IP' in globals():
    # stuff for ipython
    pass

Or check the __IPYTHON__ in builtin:

import __builtin__
if hasattr(__builtin__, '__IPYTHON__'):
    # stuff for ipython
    pass

Yes. 

if 'get_ipython' in dir():
    """
       when ipython is fired lot of variables like _oh, etc are used.
       There are so many ways to find current python interpreter is ipython.
       get_ipython is easiest is most appealing for readers to understand.
