::#Create the '''~/ops435/lab4/lab4a.py''' script. The purpose of this script will be to demonstrate the different way of comparing sets. There will be three functions, each returning a different set comparison. ::#Use the following template to get started:<source lang="python">

:::*The join_sets() function should return a set that contains all values from both sets:::*The match_sets() function should return a set that contains all values found in both sets:::*The diff_sets() function should return a set that contains all values which are not shared between both sets:::*All three functions should accept '''two arguments''' both are sets:::*The script should show the exact output as the samples:::*The script should contain no errors

::::'''Sample Run 1:'''<source>

::::'''Sample Run 2 (with import):'''<source>

<ol><li value='3' style="margin-left:40px25px;">Download the checking script and check your work. Enter the following commands from the bash shell:<source lang="bash">

<li style="margin-left:40px25px;">Before proceeding, make certain that you identify all errors in lab4a.py. When the checking script tells you everything is OK - proceed to the next step.</li></ol>
