key参数的解释: key(optional): key function where each argument is passed, and comparison is performed baased on its return value 简而言之,就是key中传递的是一个参数,此时max会根据每个传入参数后的返回值进行比较。返回值为key中的参数值 以字典为例: 1#the key whose value is the largest2square ...
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 ...
Python’s "max" function is an integral part of the language, providing the capability to retrieve the maximum value from a provided iterable object. This iterable can take various forms, such as a list, tuple, set, or dictionary. Additionally, the "max" function can accommodate multiple argu...
Pythonmax()Function ❮ Built-in Functions ExampleGet your own Python Server Return the largest number: x =max(5,10) Try it Yourself » Definition and Usage Themax()function returns the item with the highest value, or the item with the highest value in an iterable. ...
The key argument specifies a one-argument ordering function like that used for list.sort(). The default argument specifies an object to return if the provided iterable is empty. If the iterable is empty and default is not provided, a ValueError is raised. If multiple items are maximal, 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...
返回值:list #把一个序列对象转换为列表 1. 2. 3. 4. 5. 39.locals() 局部变量 格式:locals() #返回函数内部的所有变量,以字典形式返回,该函数一般不使用。 1. 2. 40.map() 映射 格式:map(function or None,iterable) 例如:print(map(lambda x:x+10,(1,2,3))) ...
