# 5.11:  Now reading from revenue.csv, sum up the values associated with each state.  (Hint:  this
# will be very much like the counting dictionary, but we will be adding float values to a sum (that
# starts at 0.0 for new keys; see the above explanation for working with keys new to the dictionary
# vs. "old" keys).)

# Expected Output:

# {'NY': 133.16, 'NJ': 265.4, 'PA': 263.45}
