What is the difference between Python and IPython?

Question

What exactly is the difference between Python and IPython?

If I write code in Python, will it run in IPython as is or does it need to be modified?

I know IPy

Answer 1

From my experience I've found that some commands which run in IPython do not run in base Python. For example, pwd and ls don't work alone in base Python. However they will work if prefaced with a % such as: %pwd and %ls.

Also, in IPython, you can run the cd command like: cd C:\Users\... This doesn't seem to work in base python, even when prefaced with a % however.
