Having some trouble with this python question. An answer would be greatly appreciated!

#Imagine you're writing the software for an inventory system for #a store. Part of the software needs to check to see if inputted #product codes are valid. # #A product code is valid if all of the following conditions are #true: # # - The length of the product code is a multiple of 4. It could # be 4, 8, 12, 16, 20, etc. characters long. # - Every character in the product code is either an uppercase # character or a numeral. No lowercase letters or punctuation # marks are permitted. # - The character sequence "A1" appears somewhere in the # product code. # #Write a function called valid_product_code. valid_product_code #should have one parameter, a string. It should return True if #the string is a valid product code, and False if it is not.

#Add your code here!

#Below are some lines of code that will test your function. #You can change the value of the variable(s) to test your #function with different inputs. # #If your function works correctly, this will originally #print: True, True, False, False, False print(valid_product_code("A12B44BP")) print(valid_product_code("BFDSAUSA98932RWEFOEWA9FEAA1DSFSF")) print(valid_product_code("A1BBD5")) print(valid_product_code("BDD5664S")) print(valid_product_code("66aBSaA1fdsv"))
