Your code will need to have some additional functions that will accomplish the following: * The output from <code>call_df()</code> should be filtered to omit any lines that contain <b>loop</b> or <b>tmpfs</b>. These are not proper file systems and should not be displayed.* The output from <code>call_free()</code> should be used to calculate a percent of <b>memory used</b> divided by <b>total memory</b>. * The output from uptime should be in "pretty" format, that is, in weeks, days, and so on. You may create this as a Python functionany other functions that you think appropriate, or especially when you may also want begin to explore another way to do thisbuild additional functionality. Part of your evaluation will be on how "re-usable" your functions are, and sensible use of arguments and return values.
