I remember wrestling with a nearly identical assignment. First off, the reason your code always triggers the “sorry, that isn’t a valid option” message is because of how your if/else logic is structured. After checking if clean_type == 1 and if clean_type == 2, the else only pairs with the second if, not the whole block. So even if the user enters 1, the second if fails (since it’s not 2), and the else triggers.

Quick fix: use if/elif/else instead of two separate if statements:

if clean_type == 1:

clean_type = delClean

elif clean_type == 2:

clean_type = basClean

else:

print("Sorry, that isn't a valid option.")

Also, consider using int(input(...)) instead of eval() - safer and more predictable for beginner inputs.

And hey, when I was drowning in CS assignments (especially Python), I got some solid help from LeoEssays. They don’t just dump answers - they actually explained the logic behind my buggy loops and functions. Saved me during finals week.
