really your code ran for me

thanks

i was running the loop like key, value in invalid_records, i had forgotten that i have to use invalid_records only. So i used your way

6

i was having trouble with this step. and i changed {val} to {dictionary[key]} like you did, and it worked. but i don’t understand why. isn’t {dictionary[key]} an integer?

7

why do you think it is an integer?

sometimes it is, sometimes it isn’t, if you look at the object you should see that it can be any value

8

right, i got confused for a moment. but i still don’t understand why {value} changed with {dictionary[key]}.

9

do you understand what dictionary is? do you remember what the dictionary[key] syntax does?

do you understand what we want to communicate with this loop?

10

i know what dictionary is. but i don’t understand whether what dictionary[key] syntax does nor what does the loop for.

11

if you don’t know what the dictionary[key] syntax does you should review how to work with dictionaries

the loop is to print infos about each invalid key/value pair found in the dictionary being analysed
