Question

A company uses codes to represent its products, for example ABC2475A5R-14. Valid codes must have:

• At least 10 characters (some codes have more than 10 characters)

• Positions 4 through 7 must be digits (and represents the country in which the product will be sold)

• The character in the 10th position must be a capital letter and represents the security level of the product.

Write a Python program that will read 10 product codes from a text file (Codes.txt - attached below). Determine if each conforms to the rules listed above:

If it does conform, print a heading: Valid Code(s) are: and list the codes that are valid. If it does not conform, print a heading: Invalid Code(s) are: and list the codes that area invalid. Be sure to test all possible combinations.

Further, if the code is valid, due to new government security laws, products with a security level of R (restricted) are no longer to be sold in countries with a country code of 2000 or higher. Output a heading: Invalid Restricted Code(s) are: and list the codes that are invalid in case you encounter any products that violate these new laws.

here is the text file data
