WebThe reduce() function in Python is used to apply a function to an iterable and reduce it to a single cumulative value. It takes two arguments: the function to be applied and the iterable to be reduced. The function is applied cumulatively to the items of the iterable from left to right, so as to reduce the iterable to a single value. WebPlot empirical cumulative distribution functions.
