Question

Write a function INDEX_LIST(L), where L is the list of elements passed as arguments to the function. The function returns another list named ‘indexList’ that stores the indices of all Non-Zero Elements of L.

For example:

If L contains [12, 4, 0, 11, 0, 56]

The indexList will have - [0, 1, 3, 5].

Answer 1

def INDEX LIST(L):
    indexList=[]
    for i in range(len(L)):
           if L[i]!=0:
                indexList.append (i)
return indexList
