The bill is split, but division often results in long decimal numbers. Since money is typically represented with two decimal places, you should round the final result.
Python provides a built-in round() function for this. It takes two arguments: the number you want to round and the number of decimal places to keep. Here's an example:
num = 4.815162342
round(num, 3) # 4.815
Use the round() function to round final_bill to two decimal places and assign the result to a new variable named each_pays.
Finally, use print() to display the string Each person pays: followed by a space and your each_pays variable.
With that, the bill splitter workshop is complete.
You should define a variable named each_pays.
({
test: () => assert(runPython(`
_Node(_code).has_variable('each_pays')
`))
})
You should use the round() function to round final_bill to two decimal places and assign the result to your each_pays variable.
({
test: () => assert(runPython(`
_Node(_code).find_variable('each_pays').is_equivalent('each_pays = round(final_bill, 2)')
`))
})
You should use print() to display the string Each person pays: followed by a space and your each_pays variable.
({
test: () => assert(runPython(`
_Node(_code).has_call("print('Each person pays:', each_pays)") or _Node(_code).has_call("print(f'Each person pays: {each_pays}')")`))
})
