Week Two Assignment 4 - File Processing Object Complete the script below to do the following: 1) Add your name, date, assignment number to the top of this script 2) Create a class named FileProcessor a) The Init method shall: i) verify the file exists ii) Extract key file system metadata from the file and store them as instance attribute required attributes: filePath, fileSize, md5Hash, lastModifiedTime, fileHeader, status, errorInfo Note: FileHeader is the first 20 bytes of the file in Hex (hint use hexlify library function) b) Create a GetFileDetails Method which will i) Return the details of the file (FilePath, FileSize, md5Hash, LastModifiedTime, FileHeader, status, errorInfo) 3) Demonstrate the use of the new class a) prompt the user for a directory path b) using the os.walk() method to extract each filename (note you will need to create the fullpath for each file) c) Loop through each filename and instantiate an object using the FileProcessor Class d) Retrieve the FileDetails for each file using the GetFileDetails method you have created e) Populate a PrettyTable with information about eachfile processed f) Print your PrettyTable g) Save and submit your PrettyTable as a csv file, along with your final python script.

This is the code I have been able to produce. I can get the code to run through everything and print a PrettyTable, but I cannot get anything to print into the table itself.
