A colleague has flattened a spreadsheet into a multidimensional list so that it can be more easily fed into a machine learning model. Unfortunately in the process, they did not correctly prepare the data. What$$s worse is that they modified the original spreadsheet so you$$ll need to process the data in this form instead of using Excel$$s convenient functionality. Machine learning models can only work with numeric values and there are still strings in this multidimensional list. You$$ll need to develop a multi$\_$sum$($multilist$)$ function. It takes a single argument multilist, which is a $2-$dimensional list. It should return the sum of all numeric types $($i$.$e$.$ int and float values$)$ from each sublist and ignore all strings. If the function receives an empty list or there are no numeric types it should return $0.$ Your function should not mutate the original list in any way. PYTHON PROGRAM
