I think when you want to jump forward it is a good sign you are enjoying learning Python and find it interesting. 
On inventwithpython url which book are you using ?
I like Al Sweigart books a lot, he is a really good teacher for Python, I have these books by Al Sweigart -
Automate the boring stuff with Python - (it is the best first book to use to learn Python imo), I am using Chapter 2 of this book.
Invent your own computer games with Python - I am using Chapter 5 of this book. (another good first choice book)
Cracking codes with Python - just looked at Chapter 1, I had to wait for some tools to make the wheels nicely.
Making games with Python and Pygame - I haven't looked at this yet it is for doing last of the first books, I am not in to games, I like code, and to see results so it's an easy way to do that etc.
Online the majority I read recommended Zed Shaw - Learn Python the Hard way, I have the Python2 version, I am on Chapter 17 of this book, but have not been using it since I began with the other books, later I will return to it. Personally I don't like this book he has a nasty attitude, that is distracting/disruptive.
The 2 chapters of Automate the boring stuff with Python & 5 chapters of Invent your own computer games with Python were enough to start making my first software/apps, it was where I began trying this.
It took me 1+ year to complete the first app, from idea to finished how I was happy with it as a first one.
It's possible to do projects at the same time as learning, and in between using the books, whenever you feel like it, or have an idea you want to try out for fun, plus you can learn extra things doing your projects, it is all practice.
