An online company needs your help to implement a program that verifies the username chosen by a new user. Their rules is described below:
Username MUST contain at least 6 characters;
Username cannot start with a number;
Username can only contain letters or numbers.
If valid, the username may be resgistered if it doesn't already exist in the system.
You should not use built-in functions to determine the character type such as isnumeric() or islower().
Use the strings given alphabet and numeric to determine if each character is valid.
Use the list registered to help you determine if the username is already registered.
Don't forget to execute the cell below to use these strings
# run this cell to create these variablesalphabet = 'ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz'numeric = "0123456789"registered = ["john87", "topmage", "light4ever", "username2"]

- The Problem__: Write a program that calculates the average of a group of test scores, where the lowest score in the group is dropped. It should use the following functions: ⚫ void getScore() should ask the user for a test score, store it in a reference param- eter variable, and validate it. This function should be called by main once for each of the five scores to be entered. ⚫ void calcAverage() should calculate and display the average of the four highest scores. This function should be called just once by main and should be passed the five scores. ⚫int findLowest() should find and return the lowest of the five scores passed to it. It should be called by calcAverage, which uses the function to determine which of the five scores to drop. Input Validation: Do not accept test scores lower than 0 or higher than 100. YOU MUST USE THE STATED FUNCTIONS AND COMPLETE Input VALIDATION. **DO NOT use an ARRAY OR GLOBAL VARIABLES!!. you MUST USE function prototyping TEST THE FUNCTION TWICE.…arrow_forwardLISP Function help please LISP Programming only A function that generates a random day of the week, then displays a message saying that "Today is ... and tomorrow will be ...". Then use the built-in function random first to generate a number between 0 and 6 (including). The expression (random) by itself generates a random integer. You can call it with one parameter to return a value within the range from 0 to the value of the parameter-1. For example, (random 10) will return a value between 0 and 9. Next, use the number generated at the previous step to retrieve the symbol for the day of the week from the list. Use the built-in elt. Extract the symbol-name of the day first, then apply the built-in function capitalize to it. Use the result in the princ function call, and do the same thing for the next day. Make the function return true (t) instead of the last thing it evaluates, to avoid seeing the message printed more than once.arrow_forward1. Retail Price CalculatorWrite an application that accepts from the user the wholesale cost of an item and its markup percentage. (For example, if an item’s wholesale cost is $5 and its retail price is $10, then the markup is 100%.)The program should contain a function named CalculateRetail that receives the wholesale cost and markup percentage as arguments, and returns the retail price of the item. The application’s form should look something like the one shown in Figure 6-22.arrow_forward
- Test Average and Grade - MUST BE WRITTEN IN PSEUDOCODEarrow_forwardOption #1: String Values in Reverse Order Assignment Instructions Write a Python function that will accept as input three string values from a user. The method will return to the user a concatenation of the string values in reverse order. The function is to be called from the main method. In the main method, prompt the user for the three strings.arrow_forwardDomino's Time Function Name: dominosTime() Parameters: N/A Returns: None Description: During the summer, you ordered a lot of food from Domino's. Pizzas are $12, an order of pasta is $6, and chicken wings are $8. Write a function that asks the user how many of each food item they would like, and then print a response telling them what their order to- tal will be. The order total should be an integer. >>> dominosTime() How many pizzas do you want? 3 How many orders of pasta do you want? 2 How many orders of chicken wings do you want? 2 By ordering 3 pizzas, 2 orders of pasta, and 2 orders of chicken wings, your order total comes to $64.arrow_forward
- Problem definition: A college wants to know how well its students did on an exam. The following program summarizes the results. The program asks a user to enter the results pass (1) or fail (2) for 10 students. It displays the number of passed and the number of failed. It displays a message "Raise error" if the number of passes is more than 8 You are asked to identify statement with syntax errors by selecting them as wrong and the correct statements as rightarrow_forwardText-based adventure game: Pretend you are creating a text-based adventure game. At different points in the game, you want the user to select to fight, run, or hide from certain enemies. Modify the application below (week3.py) so that the selection variable is sent as an argument into the choice() function. The user should enter 1 to fight, 2 to run, or 3 to hide in the main(). The choice() function should print one of the three options. You will need to add an if statement in the choice() function to make the correct selection.arrow_forwardINFS3410 Practice Questions Chapters 1, 2 and 3 The Following is an example run of an educational program for school children. The program help kids to practice their additions and subtraction skills. Your task is to develop a program that can achieve the same exact thing. Bear in mind the following important guidelines: - The user may choose between additions and subtractions - The user may choose the difficulty level (easy, medium, hard) - The program should display 5 questions and calculate the total score - No two questions should be the same Please enter your name: Hafedh AlShihi ************** Hello Hafedh AlShihi Welcome to our Additions / Subtractions Practice ****k********* Which operation you want to practice?
