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.
Thank you so much..!
one sign typing was mistaken
afterwords it went good!
