This code is used to calculate the rank of each element in a rolling window of size 10.
The rolling() function is used to create a rolling window object with a window size of 10.
The rank() function is then applied to this rolling window object. The rank() function calculates the rank of each element in the given axis, with 1 being the highest rank. The ascending=False parameter is used to calculate the rank in descending order.
So, the output of this code will be a DataFrame with the same shape as the original DataFrame, where each element represents the rank of that element in its corresponding rolling window of size 10.
