How does IPython's magic %paste work?

Question

I want to copy already indented Python code / whole functions and classes into IPython. Everytime I try the indentation is screwed up and I get following error message:

Answer 1

You can't copy to IPython directly. This are the steps:

1. Copy the lines you want to copy into IPython into the clipboard
2. Enter %paste into IPython
3. Press enter
4. Profit!
