Tic Tac Toe

Tic Tac Toe, comparing values based on difference.


#Note: this was worked out on paper before hand
#associate numbers with game input
gameDict = {
   'R':1,
   'P':2,
   'S':3
}
#turns counter
turns = 0

while True:
   #ask input
   playerOneInput = input('Player 1, choose R, P, S: ')
   playerTwoInput = input('player 2, choose R, P, S: ')

   #retrieve game dict values
   dictVal1 = gameDict[playerOneInput]
   dictVal2 = gameDict[playerTwoInput]

   #we use a difference among dict values to compare winner
   difference = dictVal1 - dictVal2

   #player one wins when diff are [-2,1,1]
   #player two wins when diff are [2,-1,-1]
   #based on the differences of dict values, either player 1 or player 2 wins
   if difference == -2 or difference == 1:
      print('player One wins')
   elif difference == 0: #draw if difference is 0, S & S, 3 - 3
      print('draw')
   else:
      print('player Two wins')

   #break out of loop after 7 turns
   turns +=1

OOP w/ Javascript

Implement a simplified filesystem using Object Oriented Programming consisting of only Files and Directories. Directories can contain Files or other Directories. Both Files and Directories should have attributes 'name', 'filesize', 'writeable'. Given a 'tree' that looks like Directory - File - Directory - Directory - File Change the 'writeable' attribute for each object from true to false

Taxonomy page show posts count

As stated in the edit:

$count = $GLOBALS['wp_query']->post_count;
Another option would be to use

$count = $GLOBALS['wp_query']->found_posts

Single taxonomy / category page

single_cat_title(); 
single_tag_title();
the_archive_description();

$term = get_term_by( 'slug', get_query_var( 'term' ), get_query_var( 'taxonomy' ) ); 
echo $term->term_group;

You can use it for the all of the following values:

term_id
name
slug
term_group
term_taxonomy_id
taxonomy
description
parent
count
