Python Love :)

[mwt]

I've only been goofing around with Python for about a month now, but
already I am in love.
I never get that feeling -- so common with Java -- that I'm swimming
upstream, struggling to force the language to do what I want.
Python makes it feel effortless and easy.

OK, I can't help it... which is more readable:

a_string.reverse (ruby)
a_string[::-1] (python)

 

[Paul Rubin]

a_string.reverse (ruby)
a_string[::-1] (python)

reversed(a_string) (python)

 

[gregarican]

reversed(a_string) (python)

Which version of Python offers this function? It doesn't seem to be
available in the 2.3 version I have installed...

I think it's new in 2.4.

I think it's new in 2.4.

Needs a little help, though:
.... def __reversed__(self):
.... return self[::-1]
....'abba'

Now if only I had picked a better example

Darn, yes, that's the second time in the past couple weeks I've made
that exact same error in a clpy post. So what's the most concise way
of turning it back into a string? ''.join(list(reversed(a_string))) ?
Bleccch.

You don't need the list(), join() can take an iterator:

''.join(reversed(a_string))

Use Ruby:

print "A String".reverse

Just kidding ~

Umm,
Did you mean to write the above?
What has it to do with Ruby?
