'Add number to a total in a for loop [closed]

I need to compute the mass of a series of objects in a list

for element in list:
    weight = "a calculation here"

How do I save the weight calculation and add it up for each time it goes through the for loop?

python

Solution 1:^[1]

for element in list:
    weight += "a calculation here"

Does this work for you?
