>>> sum([1, 2, 3, 4, 5], start=100) # Keyword argument 115 在这里,您提供初始值100to start。净效果是sum()将此值添加到输入可迭代中的值的累积总和中。请注意,您可以start作为位置参数或关键字参数提供。后一个选项更加明确和可读。 如果您没有为 提供值start,则默认为0。默认值0确保返回输入值...

详解Python的max、min和sum函数用法 max()、min()、sum()这三个内置函数分别用于计算列表、元组或其他可迭代对象中所有元素最大值、最小值以及所有元素之和,sum()只支持数值型元素的序列或可迭代对象,max()和min()则要求序列或可迭代对象中的元素之间可比较大小。下面的代码首先使用列表推导式生成包含10个随机数...
by the `kind` keyword. It returns an array of indices of the same shape as `a` that index data along the given axis in sorted order. 从中可以看出argsort函数返回的是数组值从小到大的索引值 Examples --- One dimensional array:一维数组 >>> x = np.array([3, 1, 2]) >>> np.argsort...
