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 user should enter: • The total number of calories for a food item • The number of fat grams in that food item Accordingly, the application will calculate and display: • The number of calories from fat • The percentage of calories that come from fat Additionally, the applications categorizes if the food is considered low fat, normal fat, or high fat as the following rule. If the calories from fat are less than 30% of the total calories of the food, the food is considered low fat. If the calories from fat are between 30% and 40% of the total calories of the food, the food is considered normal fat. If the calories from fat are more than 40% of the total calories of the food, the food is considered high fat. Note: Make sure the number of calories and fat grams are not less than 0. Also, the number of calories from fat cannot be greater than the total number of calories.

It should use the following functions: void getScore() should ask the user for a test score, store it in a reference parameter 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.arrow_forward
