Explanation

For Statement is used to execute the sequence of intruction repeatedly.
Range() method gives list of elements, here range() method gives list which has 1,3,5... to n or n-1.
for statement executes the instructions iteratively and for takes the elements one by one as value of i in sequential manner.
so it adds odd numbers.
