After experimenting with the First.py script and attending this weeks lecture, you are to modify$/$extend the First.py script as follows:

$1)$ Allow the user to specify a directory to process using the built$-$in Python input$()$ function

$2)$ Process each entry in that directory and report:

Full$-$Filepath, FileSize, MAC Times for each directory entry

Converting each MAC epoch value into human readable form

$3)$ Catch any errors when attempting to process files and report them

HINTS

PROMPT USER FOR ENTRY

directory $=$ input$("$Enter a Directory to Process: $")$

CONVERT EPOCH VALUES TO HUMAN READABLE UTC TIME

Epoch$=$ macTimes$[0]$

utcTime$=$ time.strftime$("\%$Y$-\%$m$-\%$d $\%$H:$\%$M:$\%$S$",$ time.gmtime$($modEpoch$))$
