Format Lines for Report
Use the following format lines to produce correctly formatted output.
Header
print( "\n\n%62s" % "Validate Passwords in Check File\n" )
Detail Line
Valid Passwords
print( "%40s\tValid" % word )
Invalid Passwords
print( "%40s\t\t\tINVALID" % word )
Where “word“ is the name used to address individual entries in the List returned
from buildList.

Process: 1. Ask the user for the name of an input file (a test file is provided). 2. Open the file for input 3. Pass the file to a FUNCTION (buildList) you will define that will: a. Accept an input file b. Return a List c. The function will read the input file, separating individual passwords and storing the passwords in a List structure. 4. Pass the List created in the previous step to a FUNCTION (buildDictionary) you will define that will: a. Accept a List b. Return a Dictionary c. Create the Dictionary based on the lengths of the passwords in the List received. Each entry in the dictionary will consist of a KEY (the password length) and a VALUE (the count of passwords of that length). See Expected Output for details. 5. Print a report based on the Dictionary created in step #4. a. Print report and column headers using provided format lines. b. Print one line per Dictionary entry, using the provided format line. c. Expected output for report is included in these instructions. 6. Produce a report indicating the validity or invalidity of each password: a. Print a report header line using the provided format line. b. Print individual detail lines for the report by: Passing each individual string to a FUNCTION (validatePassword) you will define that will: 1. Accept a string value 2. Return a boolean value 3. Determine whether the received string is a valid password based on the following rules: a. The string must be AT LEAST 8 characters long b. The string must contain AT LEAST 1 UPPER CASE letter c. The string must contain AT LEAST 1 LOWER CASE letter d. The string must contain AT LEAST 1 instance of one of the following SPECIAL CHARACTERS: $, !, &, *. 4. Return True if the string passes all tests. Return False if the string fails at least one test. • Write an output line based on the return value form the previous step, using the provided format lines.

Expected Output Password Length Report Using the provided passwords.csv file, your report should look like the one below. Your entries may be in a different order. Password Length Dictionary Entries Length Count 5 11 2 3 18 1 10 5 13 1 Format Lines for Report Use the following format lines to produce correctly formatted output. Headers print( "\n\nPassword Length Dictionary Entries") print( "%9s%20s" % ( "Length", "Count" ) ) Detail Line print( "%6d %20ed" % (key, lengthDict[ key ])) Where “key" is the variable name used in the iteration control (see "Traversing a Dictionary" in Module 05) and lengthDict is the name assigned to the Dictionary returned from buildDictionary.
