Tell us what’s happening:

I have tried simple and more detailed solutions. No pass. Console shows are indices True.

Your code so far

Pass the list [isinstance(i, str) for i in medications] to the all function

'medications': isinstance(medications, list) and [isinstance(i, str) for i in medications]

You need to edit the existing line, and not add a new line.

The line in the end will check that medicatins is a list AND that all the strings in medications are strings. All in one line

3

I did try to include an all different times. It did not work.

4

‘medications’: [isinstance(medications, list) and all(isinstance(i, str) for i in medications)]

This is what I have now No pass.

5

Why did you make the whole thing a list?

Pass the list [isinstance(i, str) for i in medications] to the all function

You did that… and then made the whole line a list. Why?

Reset the step. Just pass the indicated list to the all function, that’s all.

Pass the list…to the all function

You should be passing a list to the all() function

6

This is what I have

‘medications’: isinstance(medications, list) and [isinstance(i, str) for i in medications]

    \[isinstance(i, str) for i in medications\] to all()

I honestly am at a loss where to insert all()

7

This was pretty close:

‘medications’: [isinstance(medications, list) and all(isinstance(i, str) for i in medications)]

You put all in the correct place.

Pass the list [isinstance(i, str) for i in medications] to the all function

Here is the original code:

'medications': isinstance(medications, list) and [isinstance(i, str) for i in medications]

Can you identify the list in that line of code?
