A password log file password_log_joe_bloggs.txt has been provided with the date/time and reason the password is invalid. Read the data from the file into a list and output the list. Using the list, count the number of errors for passwords that were below the minimum length and count the number of passwords that were above the maximum length. Output the counts to the screen.

Steps:

Read the contents of the password log file and add this to a list

Output the contents of the list to the screen

Use the list to count of the number of errors for passwords that were below the minimum length and a count of the number of passwords that were above the maximum length.

Display both counts to the screen

Extra:
