The notebook contains “hint” sections that essentially give you the solution to these functions.
I recommend you review the “hint” areas, and compare them with your code for the compute_cost() function.
The most common error is in how your code using indentation. That’s how Python defines code execution blocks.
Other common errors include using global variables within the graded functions.
Tip: If you use the code from the “Hint” sections, do not just copy-and-paste the code you find there. The hint code has formatting errors that will make your code not run correctly.
