Create a Python program that:Create a file and write data containing a list of names separated by a comma. The program will receive the first name and last name data from the user and save them to appropriate variables. Once the names are separately saved, a function will concatenate the names so that they are in the last name, first name order; returning the result to an appropriate variable. This result will be put into a list and then written into a file.Follow the outline below strictly, including the variable names. This code builds upon the demo code and will help you identify how to use demo code or video to solve assignments.Complete the portions with the question marks $($i$.$e$.,..?)$#A$.$ Create and initialize the variables necessary for the program.
