Python: Int not iterable errror
<p>I'm attempting to get my feet wet with python on Project Euler, but I'm having an issue with the first problem (find the sum of the multiples of 3 or 5 up to 1,000). I can successfully print out multiples of three and five, but when I attempt to include the sum function I get the following error:</p>

<blockquote>
  <p>TypeError: 'int' object is not iterable</p>
</blockquote>

<p>Any help would be appreciated. </p>

<pre><code>n = 100
p = 0
while p&lt;n:
   p = p + 1
x = range(0, p)

# check to see if numbers are divisable by 3 or 5
def numcheck(x): 
   for numbers in x:
      if numbers%3==0 and numbers%5==0:
          sum(numbers)
numcheck(x)
</code></pre>
