How can you use Python in Vim?

Question

I waste a lot of time between Vim and Python. I find it too slow to manually copy-paste from Python to Vim and vice versa. A good broken example is:

%

Answer 1

You can execute the code, read the output on the cursor and finish with u, supposing you are executing python code. Simple and quick.

:r !python %

u

I like it over mapping and selecting-in-visual-mode, like with too-much-php, because it keeps the base simple!
