'not all arguments converted during string formatting' - what this implies?

Question

l= list(input().split())
for i in range(len(l)):
if(l[i]%2==0):
print(i)

why this code is not working?

Answer 1

list elements are not integers and u can' t use % operator.
Firt u need to convert l into a list of integers using map

l = list( map( int , l ))
