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

Copy the lines you want to copy into IPython into the clipboard
Enter %paste into IPython
Press enter
Profit!

A clarification on the steps:

First, copy target lines into your clipboard.
Type into the iPython prompt:
- If on Tkinter: enter %paste
- Otherwise: enter %cpaste
Paste (Ctrl-V) and hit enter.
Then type -- and hit enter.

For example:

In [1]: %cpaste
Pasting code; enter '--' alone on the line to stop or use Ctrl-D.
:for l in "Hello World":
:    print l,
:--
H e l l o   W o r l d

%paste requires Tkinter. If you are in ubuntu, you can install it by

sudo apt-get install python-tk

If you are on Python3

sudo apt-get install python3-tk

Then restart ipython and use %paste to paste from your clipboard.

One of the useful answers was lost in the comments, so wanted to restate it along with adding a reference for another useful IPython magic function.

First to restate what @EOL said, one way to solve OP's problem is to turn off auto-indentation by first running %autoindent and doing the paste (not needed if you are using %paste, of course).

Now to add more information to what is already there here, one more useful mode in IPython is %doctest_mode which allows you to copy paste example and test snippets from doc strings. This is also useful to execute interactive python session output that you could find in documentation and online forums, without having to first strip out the prompt strings.

As of Ipython 5 you don't need any magic command, just paste it

ipython5

Thanks to prompt_toolkit, IPython now supports:

Syntax highlighting as you type

Real multi-line editing (up and down arrow keys move between lines)

Multi-line paste without breaking indentation or immediately executing code

Better code completion interface (we plan to improve that more) Optional mouse support
