Build a Medical Data Validator - Step 44

Curriculum Help

Tell us what’s happening:

I thought my code was working until I saw my “val” and “index” values on the terminal. I don’t know what to do, I already tried using all the dict and loop methods they taught me but I’m still stuck on this. Please, I need some help (TT^TT)

Your code so far

Welcome back to the forum @Notcita_01

Take another look at these two notes:

  1. Remember that invalid_records is a list of keys that refer to invalid records in the current dictionary. You will need to take the key from invalid_records and look up the value in dictionary.

  2. Position or index refers to the current dictionary in medical_records, defined by the outer for loop in the function.

Happy coding

I’d love to say that I understood, but I’m still stuck with this.

Your new for is nested inside another for loop:

Happy coding

Nevermind, I’m such a dumbass TT^TT
The solution was easier than what I did
