Products.txt contains a list of product codes.

Open Q03a in the code editor.

Write a program to implement these requirements.

The code must:

• read each product code from Products.txt
• check each product code to ensure it contains a hyphen (-)
• write any product codes that do not contain a hyphen to a Flagged.txt file

You must use the structure given in the file Q03a to complete the program.

# Q03a - Skeleton Code
infile = open("Products.txt", "r")
outfile = open("Flagged.txt", "w")

# Your code goes here

infile.close()
outfile.close()

Do not add further functionality.
