Sum in range that meet criteria [closed]

Trying to learn a new approach.
It's the classical problem of finding the sum of all multiples of 3 and 5 below 'n'.

What I want is:

print ("The sum is: ", sum(range(1, 100)))

But with an if-statement for multiples of 3 / 5.

My question:
How can I include that if-statement for a one-line solution?

Thanks for your help. =)
