The dictionary snowfall maps keys (which represent a given month) to values that represent the amount of snowfall (in inches) for every time it snowed that month. Write code that creates a new dictionary named month_total_snowfall where the keys are months and the values are floats that represent the total snowfall for that month (the sum of the values in snowfall for that month).

Then, create a new float called snowfall_all_months whoes value is the total snowfall for all months.

snowfalls = {
'December': [0.2],
'January': [1.5, 3, 2, 2.5],
'February': [7, 2.3, 1.2, 4],
'March': [1.5, 3, 4],
'April': [0.2],
