title: Subsetting an address as house number, street, city, state in python
body: <p>I have 1 Billion addresses which are kinda in a bad format like:</p>
  
  <pre><code>'12-as FS street, 456 DLGG Area, Rand. District, Sydney, Australia 32 1020203'
  </code></pre>
  
  <p>I need the output like </p>
  
  <pre><code>Column1:12AS
  Column2: FS 456 DLGG Area
  Column3: Rand
  Column4: Sydney
  Column5: Australia
  Column6: 32
  Column7: 1020203
  </code></pre>
  
  <p>So basically i need them to be separated as <code>house number, address line, state, country, statecode, pincode</code> and remove words like <code>street, district, countryside, road etc</code>. </p>
  
  <p>Also I need to search for the most frequent words above a particular threshold. </p>
