hello, I'm working on a project that wants us to do a bank registration system.

my code is working perfectly fine to line 96( it can access customers file and check If the Id entered by the user exist)

my problem that i don't know how to access the transactions file and add the transactions that belongs to the Id entered to my (user_transaction list)

please try not to write a whole new code, just adjust mine if possible

thanks.
