reduce()函数的语法如下: reduce(function, iterable[, initializer]) 其中,function是用于执行归约操作的函数,它需要接受两个参数,第一个参数是累加器(accumulator),第二个参数是序列中的下一个元素。iterable是需要进行归约操作的序列,而initializer是一个可选的初始值,如果指定了initializer,则归约过程会从initialize...
reduce()函数是functools模块中的一个函数,其作用是对参数序列中元素进行累积,返回值是一个数值。 1,整数的累积:列表里面整数累加 from functools import reduce a=[1,3,5] b=reduce(lambda x,y:x+y,a) print('1.列表里面整数累加:',b)#输出:1.列表里面整数累加: 9 2,列表的累加:列表里面相加 from f...
代码使用了Python的functools模块中的reduce函数来对numbers列表中的元素进行累乘操作。reduce函数接受一个函数(lambda x, y: x * y)和一个可迭代对象(numbers),并依次将可迭代对象中的元素传入函数进行操作。最后返回累积计算的结果。 lambda x, y: x * y是一个匿名函数,用于实现两个数相乘的操作。 numbers...
