Create a dictionary (order_dict) that the key is the burger number, and the value is a list of the quantities.
For example: order_dict which is {'1': [10, 3, 78], '2': [35, 0, 65], '3': [9, 23, 0], '4': [0, 19, 43], '5': [43, 0, 21]}
Create a dictionary (total_order_dict) that the key is the burger number, and the value is the total of the quantities for that burger.
For example: total_order_dict which is {'1': 91, '2': 100, '3': 32, '4': 62, '5': 64}
Use "assert to test the values of the total_order_dict
For example:
expected_result_ototal_order_dict = {'1': 91, '2': 100, '3': 32, '4': 62, '5': 64}
assert actual_result_ototal_order_dict['1'] == expected_result_ototal_order_dict['1'] , "The actual result is not the \same as expected result for the order number 1!"
(and test the other elements)
The function can be like:
def test_sum(): #Testing assert actual_result_ototal_order_dict['1'] == 91, "The actual result is not the \ same as expected result for the…

If you're confused about how to do something make sure you look back at earlier assignments. In this program you will start by declaring an empty dictionary named population_dict. Then you will use a while-loop to prompt a user for a series of cities and their populations, storing the input in population_dict). After this you will prompt the user to decide what is the maximum population for a city to be considers a small down. Finally, you will open a file called populationdata.txt where you will write the results. Expected Output Example of standard out (the console): What is next city? (enter q to quit) Long Beach What is the population of Long Beach? 362000 What is next city? (enter q to quit) Los Angeles What is the population of Los Angeles? 382000000 What is next city?
