What Is the max() Function in Python and What Does It Do? In Python, the max() function returns the maximum value in an iterable or out of two or more given values. It can be used in two forms: with objects or with iterables. Unlike max() in C/C++, in Python, max() can tak...
There are two optional keyword-only arguments. Thekeyargument specifies a one-argument ordering function like that used forlist.sort(). Thedefaultargument specifies an object to return if the provided iterable is empty. If the iterable is empty anddefaultis not provided, aValueErroris raised. If...
使用max()和min()方法在可比较元素的集合(例如列表,集合或数组)中查找最大(或最小)项的Python示例。 1. Python max() function max()该功能用于– 计算在其参数中传递的最大值。 如果字符串作为参数传递,则在字典上的最大值。 1.1. Find largest integer in array ...

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...
