--description--

In this workshop, you will practice working with numbers and mathematical operations to build a bill splitter. This tool will calculate how much each person owes after adding meal costs and a tip.

To start, you need a way to keep track of the total amount as costs are added. In Python, you can use a variable to store an integer (a whole number) that changes over time.

For example, you might write:

my_number = 2

Create a variable named running_total and assign it the value 0.

--hints--

You should have a variable named running_total.

({ 
    test: () => assert(runPython(`
    _Node(_code).has_variable('running_total')
    `))
})

You should assign the integer 0 to your running_total variable.

({
    test: () => assert(runPython(`
    _Node(_code).find_variable('running_total').is_equivalent('running_total = 0')
    `))
})
