To view the newly generated file, enter the following command: ls ~/data Use instructor-provided blood or prepare the finger as previously described. Since the function contains_domain takes in email address passed as parameter, we will iterate over the user_email_list to pass email addresses one by one. Table of Contents report_file = '' + '/updated_user_emails.csv' Next, replace the email addresses within the user_data_list (which initially had all the user names and respective email addresses read from the user_emails.csv file) by iterating over the new_domain_email_list, and replacing the corresponding values in user_data_list. Next, we will use substitution function sub() from re module to replace the old domain name with the new one and return the updated email address. if user[email_index] == ' ' + old_domain: You have to now complete the function's body to make it work as intended.
