IPython

IPython (https://ipython.readthedocs.io/en/stable/overview.html) provides an extended Python command shell. Among the features that it provides, the most interesting ones are as follows:

• Dynamic object introspection
• System shell access from the prompt
• Profiling direct support
• Debugging facilities

Now, IPython is a part of the larger project called Jupyter, which provides interactive notebooks with live code that can be written in many different languages.
