Unlimited tries A computer store uses a database to track inventory. The database has a table named Inventory , with the following columns: ProductID INTEGER PRIMARY KEY NOT NULL ProductName TEXT QtyOnHand INTEGER Cost REAL Also assume that the cur variable references a Cursor object for the database. Write Python code that does the following: Executes a SELECT statement to return all the columns from the rows where QtyOnHand is less than 10 and Cost is less than 900.00. Assigns all the results of the SELECT statement to a variable named results

INSTRUCTIONS: All problems should be written using JustBASIC. The code should be typed into the JustBASIC editor and executed. At the end of each solution, you should state whether the code executed and whether it produced correct results. Failure to follow directions will result in a zero for the assignment. 1. 2. 3. Write the beginning of the program that will create five arrays of the type and name listed below. Get the number of movies to be entered into the database from the user. Be sure to initialize the arrays. STRING actorLastName STRING actorFirstName STRING nameOf Movie NUM year OfDebut NUM grossearnings Add to the previously written code the part that will allow the user to populate the arrays. Using the previously written code, add pseudocode that will search for the actor's last name. You will ask the user for the last name to be searched for. You can assume all last names are unique (no repeats). If the name is present, your program will return the string "Target found"…
C++ Write a program that will allow a user to enter students into a database. The student information should include full name, student ID, GPA and status. The program should allow delete any student based on student ID. You may not use a vecto or an array only the list function.
Write a program in Java, Python and Lisp When the program first launches, there is a menu which allows the user to select one of the following five options: 1.) Add a guest 2.) Add a room 3.) Add a booking 4.) View bookings 5.) Quit The functionality of these options is as follows: 1.) When users add a guest they provide a name which is stored in some manner of array or list. Guests are assigned a unique ID value where the first guest added is assigned the ID value 1, the second guest added is assigned the ID value 2 and so on. 2.) When users add a room they provide a room number and a room capacity (i.e. how many people can stay in the room at any one time) which is stored in some manner of array or list. Rooms have a property which indicates if they are booked or not for any given date – please see the Room Booking Dates section below for some guidance on the easiest way to implement this. 3.) When users add a booking they provide a guest ID, room number, the number…
Homework Assignment-1Topics: Functions, Dictionary, ImportProblem description: Write a python application to simulate an online clothing system. Thepurpose of this assignment is to gain experience in Python dictionary structure, create basicPython functions and import a module.Design solution: The template file contains a list of clothes item sold, each item in the listcontains the item id, name of the item and the prices. The program will generate an items_dictwhere each key is the item id of the cloth and the values will be a list of item name and priceinformation. A customer will be presented with a main menu with 4 different options: displayall items, add an item to cart, checkout and exit the program. A customer can buy an item byentering the ID of the item. This program implements a dictionary called cart, where each key isthe item id and the values are the list of name, price and quantity that user chooses topurchase. The program keeps repeating by displaying the main menu to…

Create Java statements based on the following requirements: 1. Create an empty hash map named programs that will handle keys and values that are both of String type. 2. Map the following pairs: • BSIT – Bachelor of Science in Information Technology • BSCS – Bachelor of Science in Computer Science • BSIS – Bachelor of Science in Information Systems 3. Display the keys in a single line. 4. Delete the first entry. 5. Check whether the map contains the key "BSCpE".
3. lookup_friends_heights This function takes a friends database (a list of dictionaries, like the previous functions) and a list of friends names, and it returns a list of heights for the specified friends. If a given friend's name is not present in the friends database, we put a None in the corresponding slot. We assume that there will be at most one friend with a given name in the list. You may want to use nested for-loops for this function. Sample calls should look like this. >>> lookup_friends_heights([{"name":"todd","height":170},{"name": "sarah", "height":165},{"name":"dweezil", "height":175}], ["dweezil", "sarah"]) [175, 165] >>> lookup_friends_heights([{"name": "todd","height":170},{"name": "sarah","height":165},{"name": "dweezil", "height":175}], %3D ["sarah", "elíza", "dweezil"]) [165, None, 175]
