Tarea

You have implemented the login() function, which raises errors. Implement the safely_auth() function that uses the login() function and catches errors.

  1. Create a code block to track errors (mention the keyword).
  2. Call the login() function in the error tracking block.
  3. Catch the TypeError and save its info inside the error variable.
  4. Print the error variable (error info) in the console.
  5. Catch the ValueError and save its info inside the error variable.
