How can I show the conda environment name in the IPython console?

Context

I would like to show the conda environment name in the IPython console of Spyder, so I know which environment I'm running in.
While this information is available in the status bar, it sometimes just shows conda instead of the actual environment name:

What I've tried

Printing it at startup

Spyder allows one to run code at the start of a console. However, it seems print statements are suppressed as I've added import sys; print(sys.executable):

Unfortunately nothing is shown (besides the default banner) when I create a new console.

Changing the input prompt

Spyder allows one to customize the input/output prompts in the console. However, I can't figure out how to let it evaluate code instead of writing it as text:

Question

How to show the name of the active conda environment in the IPython console of Spyder?

Solution

  • The suggestion to look at the relevant issue (this comment in particular) has brought me the following solution:

    import sys; 
env_path = sys.executable
start_env = env_path.rfind('\\', 0, len(env_path) - 12) 
end_env = env_path.rfind('\\')
env_name = env_path[start_env+1:end_env]
get_ipython().banner1=f"\nCurrent conda environment: {env_name}"

    By saving above in a file and setting it as the python startup file in the Spyder settings:

    I now get a nice message informing me of the conda environment that is used:
