Thee are ways to do it without using a for loop but they are
all more advanced rather than simpler. (And they are less
"good" than the simple program you have written in that they
are unnecessarily complicated)

You used a list comprehension in your solution, was that
covered as part of lists? If not how did you find it?

That's about as simple as it gets except for the surplus
of parens in the last line:

print(sum(nums) / len(nums))

is sufficient.
