Assignment 7 part 1 Part 1: Username & Password Validator This program has been broken into two parts. You can submit them both as one single file as the programs build upon each other. Part 1a: Username Validator You have been asked to write a username validation program for a small website. The website has specific rules on what constitutes a valid username, including: • All usernames must be between 8 and 15 characters long • Usernames can only contain alphabetic (a-z and A-Z) and numeric characters (0-9) - no special characters or spaces are allowed. • The first and last characters in a username cannot be a digit • Usernames must contain at least one uppercase character • Usernames must contain at least one lowercase character • Usernames must contain at least one numeric character Write a program that asks the user to enter in a username and then examines that username to make sure it complies with the rules above. Here's a sample running of the program - note that you want to keep prompting the user until they supply you with a valid username. User input is underlined: Enter a username: craig * Length of username: 5 * All characters are alpha-numeric: True * First & last characters are not digits: True * # of uppercase characters in the username: 0 * # of lowercase characters in the username: 5 * # of digits in the username: 0 Username is invalid, please try again Enter a username: craig123 * Length of username: 8 * All characters are alpha-numeric: True * First & last characters are not digits: False * # of uppercase characters in the username: 0 * # of lowercase characters in the username: 5 * # of digits in the username: 3 Username is invalid, please try again Enter a username: craig 123 * Length of username: 9 * All characters are alpha-numeric: False * First & last characters are not digits: False * # of uppercase characters in the username: 0 * # of lowercase characters in the username: 5 * # of digits in the username: 3 Username is invalid, please try again Enter a username: Craig123 * Length of username: 8 * All characters are alpha-numeric: True * First & last characters are not digits: False * # of uppercase characters in the username: 1 * # of lowercase characters in the username: 4 * # of digits in the username: 3 Username is invalid, please try again Enter a username: Craig123! * Length of username: 9 * All characters are alpha-numeric: False * First & last characters are not digits: True * # of uppercase characters in the username: 1 * # of lowercase characters in the username: 4 * # of digits in the username: 3 Username is invalid, please try again Enter a username: Craig123T * Length of username: 9 * All characters are alpha-numeric: True * First & last characters are not digits: True * # of uppercase characters in the username: 2 * # of lowercase characters in the username: 4 * # of digits in the username: 3 Username is valid! Hint: you will need to count the # of uppercase, lowercase and digit characters using some kind of loop. Part 1a is an intermediate step towards the final version of this program. You do not need to turn in this part of the program - keep working and turn in part 1b when you are finished. You only need to turn in part 1b. Part 1b: Password Validator This is a solo project. You may start working in your Ed workspace as a group to help each other out, but after class everyone should download any work written by the group and continue working locally on their own computer. You will be doing yourself a HUGE disservice by not working on this project by yourself! If you do share tips with one another please be sure to include everyone's name at the top of your program. Note that "sharing tips" does not mean "copied the entire program" from someone else. • Passwords must be at least 8 characters long (but they do not have an upper limit) • Passwords cannot contain the user's username (i.e. if the username is "My1stUsername" the password cannot be "abcMy1stUsername" or "My1stUsernameABC" because the username String can be found in the password String) • Passwords must be a mixture of uppercase letters (A-Z), lowercase letters (a-z), digits (0-9) and a select number of special characters (#, $, % and &). The password must contain at least one of each of these types of characters in order to be valid. • Passwords cannot contain any duplicate characters (i.e. the user cannot use the character 'a' more than 1 time in the password) You can make a copy of Part 1a and place your password validator code directly after your username validator. Here's a sample running of the program. Note that you need to continually ask the user for a password until they supply a good one. Enter a username: Craig123T * Length of username: 9 * All characters are alpha-numeric: True * First & last characters are not digits: True * # of uppercase characters in the username: 2 * # of lowercase characters in the username: 4 * # of digits in the username: 3 Username is valid! Enter a password: x * Length of password: 1 * Username is part of password: False * # of uppercase characters in the password: 0 * # of lowercase characters in the password: 1 * # of digit characters in the password: 0 * # of special characters in the password: 0 * # of invalid characters in the password: 0 Password is invalid, please try again Enter a password: Craig123T * Length of password: 9 * Username is part of password: True * # of uppercase characters in the password: 2 * # of lowercase characters in the password: 4 * # of digit characters in the password: 3 * # of special characters in the password: 0 * # of invalid characters in the password: 0 Password is invalid, please try again Enter a password: foobar * Length of password: 6 * Username is part of password: False * # of uppercase characters in the password: 0 * # of lowercase characters in the password: 6 * # of digit characters in the password: 0 * # of special characters in the password: 0 * # of invalid characters in the password: 0 * duplicate character: 'o' occurs 2 times Password is invalid, please try again Enter a password: foohellozzz * Length of password: 11 * Username is part of password: False * # of uppercase characters in the password: 0 * # of lowercase characters in the password: 11 * # of digit characters in the password: 0 * # of special characters in the password: 0 * # of invalid characters in the password: 0 * duplicate character: 'o' occurs 3 times * duplicate character: 'l' occurs 2 times * duplicate character: 'z' occurs 3 times Password is invalid, please try again Enter a password: FooHelloZzz * Length of password: 11 * Username is part of password: False * # of uppercase characters in the password: 3 * # of lowercase characters in the password: 8 * # of digit characters in the password: 0 * # of special characters in the password: 0 * # of invalid characters in the password: 0 * duplicate character: 'o' occurs 3 times * duplicate character: 'l' occurs 2 times * duplicate character: 'z' occurs 2 times Password is invalid, please try again Enter a password: xyzCraig123Txyz * Length of password: 15 * Username is part of password: True * # of uppercase characters in the password: 2 * # of lowercase characters in the password: 10 * # of digit characters in the password: 3 * # of special characters in the password: 0 * # of invalid characters in the password: 0 * duplicate character: 'x' occurs 2 times * duplicate character: 'y' occurs 2 times * duplicate character: 'z' occurs 2 times Password is invalid, please try again Enter a password: xyzCraig123 * Length of password: 11 * Username is part of password: False * # of uppercase characters in the password: 1 * # of lowercase characters in the password: 7 * # of digit characters in the password: 3 * # of special characters in the password: 0 * # of invalid characters in the password: 0 Password is invalid, please try again Enter a password: #xyz123CraigQ * Length of password: 13 * Username is part of password: False * # of uppercase characters in the password: 2 * # of lowercase characters in the password: 7 * # of digit characters in the password: 3 * # of special characters in the password: 1 * # of invalid characters in the password: 0 Password is valid! Hint: The count method may be useful for finding the # of times a character repeats within a password. This program should be named as follows: "GautamDhwani_assign7_part1.py" Assignment 7 part 2 Part 2: Simple Encryption This program asks you to build a series of functions which will be put together to create a simple encoder / decoder program for secret messages. The program has been broken into two parts. You can submit them both as one single file as the programs build upon each other. Part 2a Begin by writing the following functions using the IPO notation below. Test your code using the sample program below each function header. Function #1 # function: ascii_shift # input: a word to shift (String) and an amount to shift by (integer) # processing: shifts each uppercase character in the supplied word to another position in the ASCII # table. the new position is dictated by the supplied integer. for example, # if word = "APPLE" and num=1 the newly generated word would be: # # BQQMF # # because we added +1 to each character. if we were to call the
