In Python please:
Assume the availability of a function is_prime. Assume a variable n has been associated with positive integer. Write the statements needed to compute the sum of the first n prime numbers. The sum should be associated with the variable total.
Note: is_prime takes an integer as a parameter and returns True if and only if that integer is prime.
Please fix this wrong code.

n >0
total =0
while total <= n:
if is_prime(n):
total = total+ n
if total <= n:
total = n
n = n + 1

What makes myhexadecimalnumber a child of mynumber? which methods does myhexadecimalnumber inherit directly from the mynumber class? what can an instance of the mynumber class do? what can an instance of the myhexadecimalnumber class do? which methods are overridden? why are they overridden? how many examples of overloading are there? why was this done? where is the super keyword used? what is it doing? why isn’t the incoming value set immediately in the second myhexadecimalnumber constructor? how many examples can you find of an inherited method being called?

Why would a business likely use a java applet - to back up their data files for the business - to create a program that a customer can launch in their web browser - to create music on a powerpoint presentation - to organize files on their company directory
