'return' does two things - it specifies what values to return, and it exits the function. You can 
return as many values as you want but it has to be all from one return statement.

Just put all the values in one return:
return InitalCoumadinWeekRegimen, reduce ((lambda x,y: x+y), CoumadinValuesList), CoumadinValuesList

BTW reduce ((lambda x,y: x+y), CoumadinValuesList) is the same as sum(CoumadinValuesList)
