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 >>> nums = [1, 8, 2, 23, 7, -4, 18, 23, 42, 37, 2] >>> max( nums ) 42 #Max value in array 1.2. Find largest ...
In this example, we defined a list of strings. We then passed the list and the key parameter to the max function. The key parameter is a function that takes each element of the list and returns its length. The max function in python compares the lengths of each element and returns the ...
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...

Python内置函数max()、min()和sorted()以及列表方法sort()都有一个参数key用来指定排序规则,解决的就是这个问题。key参数应该是一个可调用对象,在Python中,类、自定义函数、内置函数、lambda表达式、带有特殊方法__call__()的对象都属于可调用函数。关于key参数的更多用法请参考文末的相关阅读。
