Write the Python code to implement the function$$title$\_$case$($s$)$where$$s$$is a string. The function returns a$$new string where the first letter of each word is capitalized, and the rest of the letters in the word are lowercase. $$ Tip: If needed split$()$and$$join$()$ built$-$in method can be useful here!$--$ Remember that material not covered in class cannot be used, thus, the string methods capitalize$(),$ lower$(),$ upper$()$ and others related to letters cannot be used here! Refer to the hands$-$on lecture videos for a baseline for treating each characater.

Example:

$>>>$ title$\_$case$(\text{'}$we Are peNN state'$)$

$\text{'}$We Are Penn State'
