R problem

1. Student records. Create an S3 class studentRecord for objects that are a list with the named elements ‘name’, ‘subjects completed’, ‘grades’, and ‘credit’. Write a studentRecord method for the generic function mean, which returns a weighted GPA, with subjects weighted by credit. Also write a studentRecord method for print, which employs some nice formatting, perhaps arranging subjects by year code.

Finally create a further class for a cohort of students, and write methods for mean and print which, when applied to a cohort, apply mean or print to each student in the cohort.

In python please Problem Create two server objects using the class create a function, biggest_server_object_sum, outside of the ServerClass class, that: 1. Takes the IP 2. Sums the octets of the IP together (example 127.0.0.1 = 127+0+0+1 = 128) 3. Returns the Server object with the larger sum Example: server_one = ServerClass("127.0.0.1") server_two = ServerClass("192.168.0.1") result = biggest_ip_sum(server_one, server_two) print(result) Hint Modify get_server_ip in the previous problem. -------------------- Please use this code to start class ServerClass: """ Server class for...
