Topics: Pseudocode, Branching, For and While Loops, Sequences, Basic I$/$OProblem description:Write a Python application to simulate a Password Storage and Management system. The purpose ofthis assignment is to gain experience in Pythons loop $($while and for$)$ structure, conditional structure,sequences, and basic I$/$O$.$Design solution:The program initially provides a menu to the user. The user can choose an operation by entering thenumber associated with that option as input. The three operations of the menu are explained below$\mathrm{.}1.$ Add username and password to the database: The program asks the user to input a username andpassword. There are no specifications for the username. However, the password must consist of sixcharacters: two upper case letters, two lower case letters, and two digits, in any order. The passwordshould not contain any other characters $($special symbols, etc.$)$ at all. An example username can beJaneDoe and a password can be Gr$81$aB$.$ The program will go on to check whether the passwordmeets these requirements or not. If successful, the program joins the username and password by a $-.$An example would look like JaneDoe$-$Gr$81$aB$.$ This string will then be appended to the globaldatabase list.Four lists, upper$\_$case$\_$letters list of all letters in upper caselower$\_$case$\_$letters list of all letters in lower casedigits list of all digitsdatabase list of username$-$password stringswill be provided to you in the template. You can use these lists accordingly. If not successful, print theerror message providing the reason along with the number of upper$-$ and lower$-$case letters and digitsin the password entered by the user.Please note: All the usernames in the database list must be unique. So$,$ when the user provides theusername as input, please check that they are not giving a username already in the database list$\mathrm{.}2.$ Displaying the list of passwords and usernames: On selecting this option, the program outputs allthe usernames and passwords present in the database at that time. You will have to split theusername and password from the username$-$password string explicitly and print them separately.Please do not print the whole sequence type as$-$is$\mathrm{.}3.$ Update the password of an existing user: The program asks the user to input the username forwhich the password is to be updated from the database list. It then finds the particular username$-$password string associated with the input username and updates the username$-$password stringfrom the database list. Display an informational message once updated$\mathrm{.}4.$ Exit$/$terminate the program.If the user enters any other option, display a message stating that the option is invalid and a requestto try again.Notes: You need to write pseudocode to plan the program, and it needs to be submitted inside thetemplate file in the Pseudocode section of the header. Helpful Code and Hints:o For password checking, while loop video lecture $3\mathrm{.}5$ in Module $3$:simple$\_$authenticaltion$\_$system.py and extended$\_$simple$\_$authentication$\_$system.pyo Menu program: $3\mathrm{.}6$ while loop use case: simple calculator application in Module $3$o Generic string and list operations: Video Lecture $4\mathrm{.}3$ and $4\mathrm{.}5$ in Module $4.$ Hint: Howcan you split a string by a delimiter?o Accessing a list database: Review how to access each item in a list using a for loopo How to update a particular item in a list $($needed for option $3)$: Think aboutupdating an item by index.Sample I$/$O: Sample I$/$O is provided for your clear understanding. You need to use the format functionto properly display the information. Please note that the sample I$/$O is only provided to clarify what isexpected from the program. You need to test your code on the given I$/$O$.$ You may change thelanguage$/$interface but the program needs to display the information as shown:Example $1$:$***$ Welcome to Password Storage and Management system $***$Available options:$1$: Add password$2$: Display usernames and passwords$3$: Update password by username$4$: ExitEnter option: $1***$ Add username and password to the database $***$Enter your username: janeDoeEnter your password $($Example: ABcd$56)$: M$8$soN$1$Password Accepted!Adding username and password janeDoe$-$M$8$soN$1$ to the database$***$ Welcome to Password Storage and Management system $***$Available options:$1$: Add password$2$: Display usernames and passwords$3$: Update password by username$4$: ExitEnter option: $1***$ Add username and password to the database $***$Enter your username: MaryUsername Mary already in database!
