Well, we all know to know the value when we have the index of a list.
But how can we find it in the reverse way... say a listl=[1,2,3,4]
l[0]=1.but how can I find its address with its value 1 ??

help ([])

 index(...)
L.index(value, [start, [stop]]) -> integer -- return first index of value.
     Raises ValueError if the value is not present.
