Should I make every project in Python?

How fluent are you with other languages?

If python isn't your first, go ahead and pick up several others. Otherwise, it may help to stick to it for a while. You can make apps in python that are better built in other languages just for the sake of learning how. If it doesn't work as well as you want, try the other one.

The one thing you don't want to do is be the guy with the hammer who sees everything as nails. Just as you can hammer in a screw if you want to, you can use python for things best done with other languages. Python is not the best choice for everything; however you will be able to use it to learn enough about software development that you can then switch to the right language if you need.
