Скачать или смотреть Python Trick: Using itertools.accumulate for Running Totals and More

The itertools.accumulate function returns accumulated sums, or any other binary function, over an iterable. By default, it computes the sum, but you can provide a different function for other types of accumulation.

How It Works:
accumulate(numbers) computes the running total of the list numbers.
accumulate(numbers, operator.mul) computes the cumulative product of the list numbers using the operator.mul function.

Why It's Cool:
Versatility: Can compute accumulated results using any binary function, not just addition.
Efficiency: Provides a memory-efficient way to compute running totals or other accumulations.
Simplicity: Simplifies the code needed for such operations, making it more readable and maintainable.

This trick is particularly useful for tasks involving running totals, cumulative statistics, and other similar operations.
