Don't worry, you will get a lot of good things by learning Python. And when you become comfortable with your first programming language learning new ones will be way faster.

The most important for newcomers is to pick one language and stick with it long enough to know it well (I would advise for a general-purpose programming language such as python). It will take time before you bump into its limits, and when that happen you can start to look around how things are being done in other languages.
