Python to Ruby Tutorial (need collborators

r

2/1/2009 4:15:00 AM

Hello all,
I am a Python programmer and a Ruby Nuby. I have not found a guide
available for Python programmers wishing to learn Ruby. I know Python
and would like to write a tut so future people in my position can make
the change easier.

Would anybody who knows the Ruby language care to get involved in this
project?

I want to set up some examples like -- How do you handle situations in
Ruby where you would use a list comprehension in Python? for example
to iterate over a container selecting the items that pass a test [obj
for obj in list if obj.attribute == this] ,etc, etc...

This would help to break the ice.

some_array.select{|item| item>5}

For example

Why not make it bidirectional? So good for ruby programmers learning
python too? I'd be interested in that.

Absolutely! Ruby<->Python.

As you know quite a bit of bad blood exists between the two languages.
This imbalance exists from a misunderstanding and/or lack of knowledge
between the other. We could really do something good here. Let's do
some talking off list and see what we can come up with! feel free to
contact me.

Bad blood? Python is one of the few languages I can pick on without
feeling like I'm in a battle of wits with an unarmed person. I think you
will find that a large number of Rubyists think highly of it.

It's not what I know that counts.
It's what I can remember in time to use.

Completely false.

There are a few people who like making inflammatory posts, that's all.
It does not reflect how the majority of users of each language feel
about the other.

I have no experience with Python, but what I've seen looks OK. I've
never had a need or desire to learn it.

I've never met a happy clam. In fact, most of them were pretty steamed.

I have >2 years flight time with Python, and I try very hard not to add to the
"bad blood" in these forums. Sometimes...

Hello,
there is something on
http://www.ruby-lang.org/en/documentation/ruby-from-other-languages/to-ruby-fr...

The german version seems to be more detailed:
