title: Run the module in python 2.7.6?
body: <p>I created a class Rectangle and try to save to a module.</p>
  
  <p>Output:</p>
  
  <pre class="lang-none prettyprint-override"><code>Traceback (most recent call last):
  File "/Users/Dropbox/using Python 3/test.py", line 2, in &lt;module&gt;
  from Rectangle import Rectangle
    ImportError: No module named Rectangle
  </code></pre>
  
  <p>My code:</p>
  
  <pre><code>import math
  class Rectangle:

          self.width = width
          self.height = height
  
      def getPerimeter (self):
          return (self.width + self.height) * 2
  
      def getArea (self):
          return self.width * self.height
  
      def setSides( self, width, height):
          self.width = width

  <p>Another file run to test Rectangle module:</p>
  
  <pre><code>from Rectangle import Rectangle
  
  def main ():
      Rectangle1 = Rectangle(4, 40)
      print  "The area  of the rectangle,", Rectangle1.width, "is width and", Rectangle1.height, "is height, are", Rectangle1.getArea()
      print  "The perimeter of the rectangle,", Rectangle1.width, "is width and", Rectangle1.height, "is height, are", Rectangle1.getPerimeter()
  
      Rectangle2 = Rectangle(3.5, 35.7)
      print  "The area of the rectangle,", Rectangle2.width, "is width and", Rectangle2.height, "is height, are", Rectangle2.getArea()
      print  "The perimeter of the rectangle,", Rectangle2.width, "is width and", Rectangle2.height, "is height, are", Rectangle2.getPerimeter()
  
  main ()
