Extend Script to All Users | Dataford Interview Questions

How would you modify your previous script to track login attempts for all users simultaneously?

Implement track_login_attempts(attempts), where each attempt is [username, successful]. Return a dictionary mapping each username to its total attempt count and failed attempt count. Preserve the order in which usernames first appear.

Input and Output

Input: a list of two-element lists containing a string username and a boolean success flag.
Output: a dictionary mapping each username to {"total": int, "failed": int}.

Constraints

0 <= len(attempts) <= 1000
Each attempt contains exactly two values: username and successful
1 <= len(username) <= 100
username is a non-empty string
successful is a boolean

Function Signature

def track_login_attempts(attempts):

Whenever you're ready, walk me through your approach or go straight to the code. The requirements are in the Question tab.
