函数max()和min()还支持default参数和key参数,其中default参数用来指定可迭代对象为空时默认返回的最大值或最小值,而key参数用来指定比较大小的依据或规则。函数sum()还支持start参数,用来控制求和的初始值。 >>> max(['2', '111']) #不指定排序规则 '2' >>> max(['2', '111'], key=len) #返回最...
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 ...
6 最后还是用help(max)来查看下英文帮助文档。Help on built-in function max in module builtins:max(...) max(iterable, *[, default=obj, key=func]) -> value max(arg1, arg2, *args, *[, key=func]) -> value With a single iterable argument, return its biggest item. The default...
分析:print(max(dic))语句默认比较的是字典的key,进行字符串的比较,一个字符一个字符的比较,根据字符的ASCII码进行比较 第二行输出print(max(dic.values())),比较的是字典的value,直接输出最大的value 第三行输出是首先将字典用zip方法将字典的value和key组成一个一一对应的元组,然后直接比较这个元组的大小 具体...
A custom key function can be supplied to customize the sort order, and the reverse flag can be set to request the result in descending order."""pass 可以看出,则几个函数第一个参数都是可变长度参数——列表,元祖,集合,字典 初级: a1=max({1,2,3})print(a1) ...
x =max("Mike","John","Vicky") Try it Yourself » Example Return the item in a tuple with the highest value: a = (1,5,3,9) x =max(a) Try it Yourself » Related Pages Themin()function, to return the lowest value.
print(np.max(my_array)) # Get max of all array values # 6…and to compute the minimum value, we can apply the min function as illustrated in the following Python code:print(np.min(my_array)) # Get min of all array values # 1...
You can find the largest element in a container in Python by using the max() function. Q2. What is the use of the max() and min() functions in Python? We use Python’s max() and min() functions to get the maximum or minimum object out of a set of objects or max/min object ...
1. 函数功能为取传入的多个参数中的最小值,或者传入的可迭代对象元素中的最小值。默认数值型参数,取值小者;字符型参数,取字母表排序靠前者。还可以传入命名参数key,其为一个函数,用来指定取最小值的方法。default命名参数用来指定最小值不存在时返回的默认值。功能与max函数相反。
Python, recognized for its simplicity, is a widely-used programming language. Within its arsenal of essential functions, the "max" function stands out. This function serves the purpose of determining the maximum value within a given iterable object. The "max" function exhibits versatility, capable...
