JavaScript, yes. Python? Python isn't particularly popular and there aren't many Python jobs around. It also isn't a particularly popular language on any platform but Linux (so while technically cross platform, if few use it on other platforms is that relevant?).
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).
