Just start from datacamp first complete one of the track either by Data Science track with python or Data Science track with R.I will suggest you start your track using python as python has wider scope than R.
After you have completed your one of the track starts with kaggle by working on a real dataset because we learn by working on real-life problems which you will find on the kaggle website along with Tutorials. After that go to advance level concept like deep learning using TensorFlow or any other framework because nowadays there are tons of resources and courses which provide better tutorials with hands-on projects.
If you want a detail explanation of Data Science then do check out Intellipaat’s blog which will help you in understanding DS.
You can get a hands-on project by referring the following Data Science Training by Intellipaat which will teach you Data Science from scratch.
And if you are more into videos then do check out the following video tutorial which will help you in mastering in the field of Data Science:
