Python scripting language use has increased by 45% since Spring 2008 according the an Evans Data North American Development Survey. Only 13% of developers used Python before Google announced its App Engine platform in Spring 2008, which at the time only supported Python, but that number has increased to 20.3% today. Other scripting language use remained relatively constant, with only small gains or losses in popularity among languages such as Ruby, PHP, Perl and Actionscript.
