Doubt Reg. Broadcasting

`1. Value Error when reshaping is not done for india and qrs . Why?

2. According to the lecture in broadcasting… the shape has to be (1,225) and (4,1) for india and qrs resp., for broadcasting to work….but only “qrs = qrs.reshape(4, 1)” is done and the code works correctly. How is this happening without changing ‘india’ from (225,) to (1,225) ?`
