how to add random numbers for each element in a list and then find average?

I'm writing a program that adds a random number for each element in a list of names and then divides the result by the length of the list to find the average. I wanted to know how to add a random number for each element in the list and then subsequently store those random numbers in a separate list. thank you!

def averageAssignment(names, assignment):

    print("Enter the student names you would like to find the average for")

    classlist = []

    while True:
        names = input("")
        if str.lower(names) == 'q':
            break
        classlist.append(names)

    for name in classlist:
        print(name)

    while 'q' or 'Q' in classlist:
        Assignemnt_Number = input(("Enter the Assignment you woudl like to average: "))
        if Assignemnt_Number == 0:
            for name in classlist:
                import random
                names = classlist.index(name)
                print("The average of assignment #" + Assignemnt_Number + "is: ")
                print (random.randint(1,101)*classlist[names])
        if Assignemnt_Number == 1:
            for name in classlist:
                import random
                names = classlist.index(name)
                print("The average of assignment #" + Assignemnt_Number + "is: ")
                print (random.randint(1,101)*classlist[names])
        if Assignemnt_Number == 2:
            for name in classlist:
                import random
                names = classlist.index(name)
                print("The average of assignment #" + Assignemnt_Number + "is: ")
                print (random.randint(1,101)*classlist[names])
        if Assignemnt_Number == 3:
            for name in classlist:
                import random
                names = classlist.index(name)
                print("The average of assignment #" + Assignemnt_Number + "is: ")
                print (random.randint(1,101)*classlist[names])
        else:
            return -999

averageAssignment(classist, Assignment_Number)
