Paste formatted Python code in command line

Question

I want to run Python code from an example in the Anaconda shell. Unfortunately the statement I want to paste has lines starting with .... Is there an easy way to run such a statement without having to manually remove the ...? I know that other shells exist, but I don't want to have to try getting them working with Anaconda

>>> features  = array([[ 1.9,2.3],
...                    [ 1.5,2.5],
...                    [ 0.8,0.6],
...                    [ 0.4,1.8],
...                    [ 0.1,0.1],
...                    [ 0.2,1.8],
...                    [ 2.0,0.5],
...                    [ 0.3,1.5],
...                    [ 1.0,1.0]])

This is where notepad++ shines as the best text editor ever. — Shashank

Notepad++ lets you delete columns from a select number of rows. You can literally take out all those dots and spaces by just holding down alt, highlighting it and hitting delete (pretty much a 2 second operation). I'm sure there are other advanced text editors out there that let you do the same. — Shashank

@Josh At just the slightest glance, it looks very slick. Thanks for the reference, I'm downloading it now. — Shashank

Python's native doctest parser is used to dealing with those pesky repr prompts. :)

>>> from doctest import DocTestParser
>>> repr_code = '''
... >>> features  = array([[ 1.9,2.3],
... ...                    [ 1.5,2.5],
... ...                    [ 0.8,0.6],
... ...                    [ 0.4,1.8],
... ...                    [ 0.1,0.1],
... ...                    [ 0.2,1.8],
... ...                    [ 2.0,0.5],
... ...                    [ 0.3,1.5],
... ...                    [ 1.0,1.0]])
... '''
>>> p = DocTestParser()
>>> code = next(filter(None, p.parse(repr_code.strip()))) # Filter out the useless parts
>>> print(code.source)
features  = array([[ 1.9,2.3],
               [ 1.5,2.5],
               [ 0.8,0.6],
               [ 0.4,1.8],
               [ 0.1,0.1],
               [ 0.2,1.8],
               [ 2.0,0.5],
               [ 0.3,1.5],
               [ 1.0,1.0]])
>>> array = list # Because it's cheaper than numpy
>>> exec(code.source) # If you're feeling very lucky...
>>> len(features)

I guess that works, but they really need to build something into the shell

As far as I understand you correctly: you want to remove dots. I would do it this way:

open up vim
press i
paste the text (ctrl+v)
press ESC to exit Insert mode
press ctrl+v to enter Visual Block
move cursor up to select all dots
press x to remove them.

Than do what ever you want with this formated text (can copy and paste)

That works, I'm just surprised that the console doesn't have an easy manner of running code copied from the web
