Hi Brent you should use the variables you've created at each stage and let python do the calculations:

years = 24
days = years * 365
weeks = days / 7

Yes, I believe using the division operator always returns a float.

As Iain said when you divide two numbers you get back a float. Try the lines above in the python shell and then use the type() function to see the class of each variable. type(years) and type(days) will return <class 'int'> and type(weeks) returns <class 'float'>. Now, there is a float() function in python that converts a number to a float. If you type years in the python shell and press enter you will get back 24. Now try the following line in the shell:

years = float(years)

and then type years again in the shell and press enter. This time you get back 24.0 which is a float.
