如何在python的生成列表中平方和添加数字？

Question

对于作业，我必须将生成列表中的每个数字平方或立方体并将它们一起添加。到目前为止，我已经使用list函数在用户输入的两个值之间创建一个列表，并尝试对每个数字求平方，但我还没有将它们加在一起。我不知道从这里到底要做什么，因为我遇到了某种生成器错误。

squares = "squares"
cubes = "cubes"
exit = "exit"

command = input("Please enter a command ('squares,' 'cubes,' or 'exit' to terminate): ")


while True:
    if command == squares:
        integer = int(input("Please enter an initial integer: "))
        term = int(input("Please enter the number of terms to be generated: "))

        for x in range(integer, integer+term+1):
            sqnums = (x**2 for x in range)
            print(sqnums)
        command = input("Please enter a command ('squares,' 'cubes,' or 'exit' to terminate): ")

    if command == cubes:
        integer = int(input("Please enter an initial integer: "))
        term = int(input("Please enter the number of terms to be generated: "))

        command = input("Please enter a command ('squares,' 'cubes,' or 'exit' to terminate): ")

    if command == exit:
        print("Goodbye")
        break
