python 3.x - sum values of same key names in a dictionary

Question

I have this dictionary that has an arbitrary number of keys which are dates, I'm trying to sum up the income of each key, my problem is I don't the number of keys at any given point.

Here is the dictionary

        Tax_table = {
            "2021-01-16": {
                "Income": 400.19,
                ...other key, values...
            },
            "2021-01-18": {
                "Income": 578
                ...other key, values...
            },
            "2021-01-21": {
                "Income": 1877,
                ....other key, values...
            }
        }

Is there a way to sum up all incomes of the table?

Answer 1

If you want to sum up all incomes of the table, the below code will work:

total_sum = 0
for i in Tax_table:
    total_sum = total_sum + Tax_table[i]['Income']
    
print(total_sum)
