There was a discussion a while back in trying to get Ruby looking like Python using an indentation scheme and I posted a possible solution to that http://xtargets.com/snippets/posts/show/68 There is also the Lazibi library ( sorry no link .. google it ) that does a similar thing. I thought to be fair I'd have a hack in the opposite direction and see if I could emulate Ruby's block notation in Python without preprocessing. Turns out that you can get pretty close though if a bit ugly due to the statement vs expression nature of the language. Note that in python a return statement from within a function with a yield statement is illegal some some ugly workaround is necessary. A few short examples ..... from ruby import rubyfi #Ruby's inject method @rubyfi def inject(ret, iter, a = 0): for x in iter: a = yield a, x ret(a) #Ruby's collect method @rubyfi def collect(ret, iter): r =  for x in iter: x = yield x, r.append(x) ret(r) # Do a sum over a range for r, s, x in inject ( range (1,6), 1 ) : r(s+x) print r() # Generate a list for r, s, x in inject ( range (1,6),  ) : s.append(x*x) r(s) print r() # Collect some items for r, x in collect ( range (1,6) ) : r(x+x) print r() The library and some details is at http://xtargets.com/snippets/posts/show/74 Can this be developed a little further or a little cleaner?
