Expanding a data set

You're given a set of data that is aggregated on a monthly basis (as illustrated in Table A).

Can you write code that can expand this monthly table into a daily table that spreads revenue across the 30 day period (as shown in Table B)?

You can assume each month has 30 days and that Table A is in a dataframe named "df".

Table A

index	Month	Revenue ($)
0	1	300
1	2	330
2	3	390

Table B

index	Month	Day	Revenue ($)
0	1	1	10
1	1	2	10
2	1	3	10
...	...	...	...
30	2	1	11
31	2	2	11
...	...	...	...
60	3	1	13
...	...	...	...
89	3	30	13
