• print() statements
• Change zip() to list(zip()) as zip behavior changes
• Change iteritems() method for items() in dict types
• Encoding latin1 because of utf8 errors in building names in development_projects.csv
• Replacing StringIO to io`
• Add sys.path.append('baus') in models.py as module baus was not loading
