Hello guys, i need your help. I am really confused with the step 8 of the project. I am writing the code like that:
percentage3 = len(visit_cart_checkout_purchase[visit_cart_checkout_purchase['purchase_time'].isnull()]) / len(visit_cart_checkout_purchase[~visit_cart_checkout_purchase.checkout_time.isnull()])
print(f"{percentage3 * 100}%")
The result is:
555.688622754491%
The codecademy solution instead which is very logical by the way is:
reached_checkout = all_data[~all_data.checkout_time.isnull()]
checkout_not_purchase = all_data[(all_data.purchase_time.isnull()) & (~all_data.checkout_time.isnull())]
checkout_not_purchase_percent = float(len(checkout_not_purchase)) / float(len(reached_checkout))
print("% of users who got to checkout but did not purchase:",checkout_not_purchase_percent)
Result:
% of users who got to checkout but did not purchase: 0.17147707979626486
I can not understand why my solution does not work and i do not also understand the solution of codecademy. Any hints on that guys 
?
