Add copy to clipboard from IPython!
To install, just copy it to your profile/startup directory, typically:
 
~/.ipython/profile_default/startup/
 
Example usage:
 
%clip hello world
# will store "hello world"
a = [1, 2, 3]
%clip a
# will store "[1, 2, 3]"
 
You can also use it with cell magic
 
In [1]: %%clip
...: Even multi
...: lines
...: work!
...:
 
If you don't have a variable named 'clip' you can rely on automagic:
 
clip hey man
a = [1, 2, 3]
clip a
