set$\_$a $=$ sys$.$argv$[1$:$]$

set$\_$b $=[\text{'}$apple$\text{'},$ 'banana', 'mango', 'orange'$]$

The above set$\_$a is a list$-$type variable which contains words.

Your order may be different for the examples below because sets are unordered.

Create a program, commonset.py$.$ Your program should:

Find the common words between set$\_$a and set$\_$b$.$

Print the output in a set format.

Example $1-$ If the set$\_$a is $[\text{'}$apple$\text{'},$ 'banana', 'pear', 'grape'$],$ the program should print:

$\{\text{'}$banana$\text{'},$ 'apple'$\}$

Example $2-$ If the set$\_$a is $[\text{'}$mango$\text{'},$ 'mango', 'mango', 'pear', 'grape'$],$ the program should print:
