$7\mathrm{.}7\mathrm{.}4$: Complete the function that parses the command line arguments.

Complete the following function that parses the command line arguments for a program that can be used to copy a text file and

returns the argument data in a list. The function should assume the program requires two arguments and allows for one optional

argument:

$-$d adds a blank line between the lines in the destination file. The default is single$-$spaced lines.

For example,

python

filecopy.py report.txt $-$d reportdbl.txt

Copies the text file report. txt to reportdbl. txt with the lines double spaced. Assume the first non$-$switch argument is the

source file name and the second non$-$switch argument is the destination file name. If a sufficient number of arguments are not

provided or an invalid switch is provided, the function should return an empty list.Parses the command$-$line arguments and returns the data in a list. The@param args list of command$-$line arguments passed to the programwhere srcfile and destfile are strings and dblspace is a Boolean. Ifswitch is provided, an empty list is returned.def parseArgs$($args$)$:
