Python is Python! [A1]关于reduce函数的參数及解释: reduce(function, iterable[, initializer]) Apply function of two argumentscumulatively to the items of iterable, from left to right, so as to reduce theiterable to a
from left to right, so as to reduce the sequence to a single value. For example, reduce(lambda x, y: x+y, [1, 2, 3, 4, 5]) calculates (((1+2)+3)+4)+5). If initial is present, it is placed before the items of the sequence in the calculation, and serves as a default ...
Even multiplying numbers isn't a great example of reduce:>>> from functools import reduce >>> numbers = [2, 1, 3, 4, 7, 11, 18] >>> reduce(lambda x, y: x * y, numbers) 33264 When multiplying it's better to use the prod function in Python's math module (added in Python ...
Python---reduce原来是这样用的 官方解释: Applyfunctionof two arguments cumulatively to the items ofiterable, from left to right, so as to reduce the iterable to a single value. For example, reduce(lambda x, y: x+y, [1, 2, 3, 4, 5]) calculates (((1+2)+3)+4)+5). The left ...
For example, reduce(lambda x, y: x+y, [1, 2, 3, 4, 5]) calculates (((1+2)+3)+4)+5). If initial is present, it is placed before the items of the sequence in the calculation, and serves as a default when the sequence is empty. 从...
python example.py # 后运行一些work python mincemeat.py -p changeme [server address] 之后server端会返回计算结果,不过这次工作节点端返回了一个warning,说是asynchat要被移除了,得用asyncio替代。下面我们也可以尝试一下更新这个库。 文件主体包括5个类和1个函数。

For example, reduce(lambda x, y: x+y, [1, 2, 3, 4, 5]) calculates (((1+2)+3)+4)+5). The left argument, x, is the accumulated value and the right argument, y, is the update value from the iterable. If the optional initializer is present, it is placed before the items ...
