Usernames
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"]
Write a function nameValidation which receives a String argument name. This function:

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.
