Iterate through three lists multiple times sequentially picking one element from a list in each iteration

I want to iterate through each of the three lists sequentially picking one element from each list in every iteration.

subjects=["Americans","Indians"]
verbs=["plays","watch"]
objects=["Baseball","cricket"]
for i,j,k in zip(subjects,verbs,objects):
    print(i,j,k)

The above code gives the output as follows:

Americans plays Baseball

Indians watch cricket

But the intended output is:

Americans play Baseball.

Americans play Cricket.

Americans watch Baseball.

Americans watch Cricket.

Indians play Baseball.

Indians play Cricket.

Indians watch Baseball.

Indians watch Cricket.

You can iterate as such for the solution:

subjects=["Americans","Indians"] 
verbs=["plays","watch"] 
objects=["Baseball","cricket"]


for s in subjects:
    for v in verbs:
        for o in objects:
            print(s,v,o+".")
