Please avoid arguments like "if you learn Python you can also use it for other things", "indentation > brackets" and "Python have Django". PHP5 frameworks are mature and solid, if you don't know about PHP's ecosystem evolution please avoid posting here. We all know Wordpress suck, just let it go.
Being honest, the reason I'm considering moving our team to Python is because of all the hate on PHP and the opinions that "PHP is the reason we can't use better languages". And I can't see a reason besides "it's a better language". I'm working with good PHP devs, TDD improved your codebase immensely and we have no problems scaling our tools and apps.
