Codes below are supposed to filter out elements which are not numbers from a given

list A$,$ and calculate only the sum of elements which are numbers. The correct output

of below codes should be $7+4j.$ At current state, there are errors in the codes. State

what are the errors, what is the output at current erroneous state, and provide the

corrected version of the codes.

def sumofNumber $(x,y)$ :
