title: Is there something in python i can use to represent any positive whole number
body: <p>Id like to know if there is something specific in python that simply represents any whole number. Specifically I want to know this so I can use said specific something (symbol or built in function I guess) to use in a search algorithm. This is so i dont have to search for precisely the right numbers just the first set of data with 2 of the right numbers and one whole positive number.</p>
  
  <p>This is the code im using for this:</p>
  
  <pre><code>def pheromone():
  '''function to measure the level of pheromone (whilst slowly depleting that level) in the grid cells in order to increase or decrease the likelihood an ant will choose that grid cell'''
      grid_list[grid_list.index([ant_position[0],ant_position[1],SOMESYMBOL])]
  </code></pre>
  
  <p>The grid list is a list containing lists. So im searching for the first list out of the grid list to have the two set values im looking for (ant_position[0] and ant_position[1]) and one arbitrary value that could concievably be any whole positive number displayed here as SOMESYMBOL.</p>
  
  <p>Any one got any ideas? </p>
