I'm looking towards enrolling on the Data Engineer with Python Career Track but before I enroll on that I'm working through the requisite skill tracks... so I've completed Python Fundamentals and now just started the Python Programming Track.
Alongside doing the Python Fundamentals track I was working my way through the Edabit challenges (https://edabit.com/challenges/python3) and reading through the other coders answers and comments. This also introduced me to various resources where I could widen my knowledge or refer to when I'm stuck on any concepts introduced in DataCamp.
I found this really helped reinforce what I was learning in the DataCamp course and especially when I got to the Data Science Toolbox course everything slotted together nicely, I'd been picking up little bits like list comprehension, lambda and function writing through the Edabit Challenges.
I'm a complete coding novice and only have a limited amount of time to study each day (this maybe helps me as I'm just taking in a couple of new concepts each day rather than whizzing through too much material at once)
