Adding Calculated Values into a list

Hi I'm curious as to how I might take calculated values and put them into a list that I can then sum when doing a backtest.
Below are 2 if statements and I want to use them to add values to a list.

if change_indicator > 0 and price_change_prev > 0:

this is where I want to add a value to a list

if change_indicator < 0 and price_change_prev < 0:

this is also a place where I want to add a value to the same list

I eventually want to sum the whole list and then print a singular value

You can use .append to add a new value to a list: https://docs.python.org/2/tutorial/datastructures.html.

Then use a for loop to sum the values and the print function to print the value or record on a graph.
