This is a question from Python class. We have to use dictionary. How to do it?

1. Here is the sample of the text file (datafile) for the tea sales (tea.txt). You have to create this file yourself Green Tea:8580.0:7201.25:8900.0 Earl Grey:10225.25:9025.0:9505.0 Ceylon 6700.1:5012.45:60110 Jasmine:9285.15:8276.1:8705.0 Mint Tea:7901.25:4267.0:7056.5 The data reads as follows-tea_name:store1_Sales:store2_Sales:store3_Sales 2. The output displayed as follows: Ceylon Earl Grey Green Tea Jasmine Mint Tea 6700.10 5012.45 6011.00 17723.55 10225.25 9025.00 9505.00 28755.25 8580.00 7201.25 8900.00 24681.25 9285.15 8276.10 8705.00 26266.25 7901.25 4267.00 7056.50 19224.75 42691.75 33781.80 40177.50 The last row is the store totals for all the kinds of tea leaves sold. The last column is the total sale for each kind of tea leaves sales. 3. 4. Write a program to read in the tea .txt textfile and then print the report as shown in #2 above. You must use dictionary. You can also use list, tuples, sets if necessary
