title: i and j equivalent in python
body: <p>I was wondering what the equivalent of "i" and "j" in C++ is in python. What I am trying to do is add each number in one set to the corresponding one in another (i.e. in the example below: [2+1], [4+3], [6+5]) I am trying to teach myself python off the internet, and I couldn't find how to do this. [example below doesn't work.]</p>
  
  <pre><code>even = [2,4,6]
  odd = [1,3,5]
  both = []
  for i in range even[]:
      for j in range odd[]:
          if(i==j):
              both.append(even[i] + odd[j])
  print(both)
  </code></pre>
  
  <p>I tried doing this:</p>
  
  <pre><code>for number1 in even:
      for number2 in odd:
          if(number1==number2):
              both.append(number + number2)
  </code></pre>
  
  <p>but this only performs addition if the numbers themselves are equal, which is not what I want. Any help would be appreciated. Thanks!</p>
