I have question about python library

In the C1_ W3_Lab06_Gradient_Descent_Soln lab,

I am not getting the lab_utils_common and plt_quad_logistic and also not getting on the google,
what it is?
how to see there code?

These files are visible via the notebook’s File → Open menu.

I am not getting it. Please tell me in detail.

Go to the notebook. Click on File → Open. You will see lab_utils_common file. Open that file, you will see the helper functions that are getting referenced in the notebook.

In the notebook, click on the “File” menu. Then click on “Open”. You will see a list of the .py files that are included in the assignment.

Click on any file name to open it, so you can read the code.

yeah got it now, thanks
