If you've been ignoring other languages to concentrate on Python of all things in the last few years then you have missed the gravy train. Object C, Java, and C are the most popular, and both Java and C are cross-platform (and better still actually used cross-platform unlike Python).
As an aside I see significantly more Java, PHP, and C# jobs than any other language (mostly for web-apps). Then after those I see pure mobile development (Java-Android, and Object C).
