Rolling
The rolling
method in Python is used to create a rolling
window
of a certain size on a time series or other data. It takes one or more parameters: the window size, and optionally the type of window (e.g. boxcar, hamming, etc.). It returns a new object that behaves like a moving window on the original data. You can then perform various operations on this windowed data, such as calculating the mean, sum, or standard deviation.

parameter specifies the size of the rolling window.mean()
: This method calculates the mean value over the rolling window. It returns a new DataFrame containing the rolling mean values.print(df)
: This function prints the rolling mean DataFrame to the console.
