I'm a mentor and project reviewer at Udacity for Data Analytics.
I've guided hundreds of students in completing their course.
When they get stuck and come for help, here is the 3 step method I tell them to use to move forward: ๐ ๐งต
1. #Python/Pandas/API documentation ๐
Go straight to the source.
Python/Pandas is well organized so you can find the source of the problem.
Try to trace your problem and use the documentation for the function/method issue.
