Ruby

I think what might help is some examples of each, like "here's how you'd do *this* in Python, and here's how you'd do the same thing in Ruby"...

again, I agree.


So I'll start off with the classic:

Code: Select all

>>>print "Hello World!"
Hello World!

This is what the interactive interpreter would do. (Code blocks are after >>>, output is plain text.)
How does Ruby handle that?

For Ruby, one would write:

Code: Select all

puts "Hello World!"

and the output would be:

Code: Select all

Hello World!

If one were to enter:

Code: Select all

print "Hello World!"

into Ruby, the output would be:

Code: Select all

Hello World!=> nil

Code: Select all

Hello World!

If one were to enter:

Code: Select all

print "Hello World!"

into Ruby, the output would be:

Code: Select all

Hello World!=> nil

OK, and Revolution would do:

Code: Select all

answer "Hello World!"

But how about something a bit more significant? Like some text parsing? Say you had a text string and you needed to count the number of words in a sentence. How would you do that in Python and Ruby?

[DarkFlame]

In python:

Code: Select all

len("Hello world!")

would output:

Code: Select all

12

[stykzman]

In python:

Code: Select all

len("Hello world!")

would output:

Code: Select all

12

That's the number of *characters*, not the number of *words*. The output should be "2" in this case... so how would you determine the number of words in Python?

I would personally use Regular expressions to find all the spaces, but I'm too tired to think about REs right now.

Look, to tell the truth, I'm a real Ruby n00b. So I have no idea how one would accomplish this. I can get Ruby to count the number of characters, I think. I saw it written somewhere, so I'm pretty sure. But a quick Google search has revealed many different confusing methods to accomplish the counting of words.

Is Ruby th Ruby on rails thing?

[DarkFlame]

ok nevermind, I found how to do it in Python:

Code: Select all

import string
words = string.split("Hello World!")
len(words)

The output would be:

Code: Select all

2

Cool... it looks like you don't need to provide a character to split on; Python assumes a space unless you provide a delimiter, right?
