title: Combining two lists of ints, into one list of strings
body: <p>Edit: I've realized my error (if statement, variable x is assigned to element in string and i'm comparing to length of list).. Trying to resolve that tomorrow morning. Appologies for the stupid error but i would appreciate any bits of learning.</p>
  
  <p>I'm trying to combine two lists into a single list.</p>
  
  <pre><code> m = [1,2,3]
   n = [4,5,6]
   v = m+n
  
   def myFun():
     return [(str(x)+str(y)) for x in m if x &lt; len(m) for y in n if y &lt; len(n)]
  
   print(myFun())
  </code></pre>
  
  <p>the result of myFun() should display "14, 25, 36"</p>
  
  <p>i also tried to breakdown the code into a more pythonic world and have seen where i've gone astray:</p>
  
  <pre><code> def my(fun()):
     for x in m if x &lt; len(m):
       for y in n if y &lt; len(n): # problem here, running until count 9 instead of 3
                                 # like it's supposed to.. author error.. 
         newlist.append(str(x)+str(y))
     print(newlist)
  </code></pre>
  
  <p>Am i even headed in the right direction or should i be trying to build a map, i've seen a few pages saying that maps could be counter-productive if you have to reverse with a list-comp or lambda? Also, is it possible to count a specific object inside a list comprehension / lambda? (e.g. list length)?</p>
