Trouble with code

strawberryunicorn (16)
I got Part 1 to work, but having trouble with Part 2 of the problem.


Question:
Part 1:
The program outputs a table of the last 12 months rainfall and average rainfall, and how much above or below average the rainfall was for each month. First it asks the current month and has the user input the actual rainfall for each month and the average rainfall for each month.

Part 2:
After you have completed the previous program, produce an enhanced version that also outputs a graph showing the average rainfall and the actual rainfall for each of the previous 12 months. There should be two bar graphs for each month and they should be labeled as the average rainfall and the rainfall for the most recent month. Your program should also ask whether the user wants to see the table or the bar graph, and then should display whichever format is requested. Include a loop that allows the user to see either format as often as the user wishes until the user requests that the program end.

(The graph should print asterisks to show the bars. For example if the rainfall for January was 5 and the average was 7 it would print:
"Jan:
Rainfall *****
Average: *******"

and I can't figure out how to switch between the tablechart and graph. The program goes wonky when inputting 't' for table and 'g' for graph.
