How to create a list containing the sums of the elements in each tuple?

I am asked to make a function that sums the elements in each tuple

data = [(1,2), (3, 4, 5), (10, 20, 30, 40)]
print(tuple_sums(data))

The result must be

[3, 12, 100]

My wrong answer is below. It can only return one sum of the tuple:

def tuple_sums(tuples):
    """returns a list containing the sums""" 
    thesum = 0
    for i in tuples:
        thesum = thesum + i
    return thesum

How can I return a list of sums instead of just one sum?

List comprehensions are a cool feature:

[sum(x) for x in data]
# => [3, 12, 100]
