Code: [Select]

import sys
sys.stdout.write("Your favorite food is " + favfood + ", huh?")

Though it's debatable if you could say that's a "right way to do it" using any sense of the phrase.

Hey, if it's stupid but works, it isn't stupid.

i would either be a really good engineer or a really bad one

Maxim 43:  If it's stupid and it works, it's still stupid and you're lucky.

Actually I'll support that method existing, because string concatenation is a thing you want in your scripting language. The + operator concatenates strings. Being able to pass through the result to any function that takes a string is an inevitable ability.

Sure, you can get rid of that way to do it, and promote the format-string method, but would you prefer to always have to concatenate strings by using printf-style formatters?

Let me rephrase.

Importing sys and writing to stdout is probably not the right thing to do if all you want can be handled by "print(stuff)", unless you're doing something special with print (say, logging output to somewhere other than stdout).

I'm writing a Python script to periodically check my Facebook page in the background, for... reasons. I'm really not sure what the point of this project is.

I refuse to believe that Facebook is written by a sane human being. A typical post contains 20+ sub-elements, and that's without the like buttons and comment section and stuff like that. I don't much about HTML aside from what is required to use Selenium, but I'm sure there's got to be a simpler way to do that.

Unless it's actually an ingenious plan to keep script kiddies like myself from scraping posts, in which case it was a brilliant 100% success.

Sometimes you want to use the DOM selectors, and other times you want to use regex's to find the stuff. You can cut through a lot of junk by being clever that way.

How do you even GUI in Java?  Good grief...

Facebook is a lot like Google.

NetBeans comes with a GUI editor that supports Swing and the other one whose name I forget.

When in school we learned to use some website making software and the HTML produced was often odd like you describe.

That is a sign of generated code, yeah. The good part of generated code is most of the time the sub-elements will be in exactly the same order with the same classes and stuff. BeautifulSoup4 for python should help you make sense of the tags and extract data.

Also, I'd be surprised if Facebook dind't have an API, a la Twitter.

[Orange Wizard]

Facebook does have an API, but it's vile.

Okay, I understand what recursive methods are, and how they can be useful, but how can I make an iterative method into a recursive one? This new kind of logic is defeating me at the moment.

Here's an example.

Code: [Select]

public class printArray
{
// initializes values
public static void main ( String args[] )
{
int array[] = { 81, 22, 18, 34, 44, 21, 94 };

for ( int count = 0; count <= 6; count++ )
System.out.print( array[count] + " " );
}
}
This will output the contents of the array with spaces between them. How can I make that recursive?

[Skyrunner]

weeell... for one, that wouldn't be a very good algorithm to make recursive, but if you really wanted to...


public static void main ( String args[] ) {
  int array[] = { 81, 22, 18, 34, 44, 21, 94 };
      
  helper(array);
}

public static void helper( int[] array ) {
  helper(array, 0);
}

public static void helper( int[] array, int index ) {
  if (index == array.length) {
    return;
  }
  System.out.print( array[index] + " ");
  helper(array, index + 1);
}

The call stack would look like:

helper(array)
  helper(array, 0)
    helper(array, 1)
      helper(array, 2)
        helper(array, 3)
          helper(array, 4)
            helper(array, 5)
              helper(array, 6) <- exits here.
