It sounds like you're in search of a solution without a problem.

Programming language for what exactly? When you know what the intended use case is, you'll probably have a reasonable idea of what you need.

Some projects might warrant all kinds of different programming languages. If you're looking at server-side security for a website then maybe it's Python, PHP, or Ruby. Embedded systems are probably not running PHP. If you're talking about reverse engineering an application then maybe learning IDA's C-like scripting language is best.

Being able to understand syntax and nuance of a language reasonably quickly are probably more important than programming in any specific language, unless you're pursuing a career specializing in one type of system. In that case you would likely know which programming languages are appropriate.
