3. Price Check - RPA

There is a shop with old-style cash registers. Rather than scanning items and pulling the price from a database, the price of each item is typed in manually. This method sometimes leads to errors. Given a list of items and their correct prices, compare the prices to those entered when each item was sold. Determine the number of errors in selling prices.

Example

products = ['eggs', 'milk', 'cheese']  
productPrices = [2.89, 3.29, 5.79]  
productSold = ['eggs', 'eggs', 'cheese', 'milk']  
soldPrice = [2.89, 2.99, 5.97, 3.29]  

The second sale of eggs has a wrong price, as does the sale of cheese. There are 2 errors in pricing.
