Reverse a word in Vim

Question

How can I reverse a word in Vim? Preferably with a regex or normal-mode commands, but other methods are welcome too:

word => drow

Answer 1

Well you could use python itself to reverse the line through the filter command. Say the text you had written was:

Python

You could reverse it by issuing.

:1 ! python -c "print raw_input()[::-1]"

And your text will be replaced to become:

nohtyP

The "1" in the command tells vi to send line 1 to the python statement which we are executing: "print raw_input()[::-1]". So if you wanted some other line reversed, you would send that line number as argument. The python statement then reverses the line of input.
