max_value = max(dct.values()) max_key = max(dct, key=lambda k: dct[k]) print(max_key) # 输出 'orange' 在上面的例子中,我们首先使用max函数获取字典中的最大值。然后,我们使用key参数来查找该值所对应的键。key参数的值是一个lambda函数,接受一个键作为参数,并返回该键所对应的值。这里的lambda...
在Python编程中,字典(Dictionary)是一种非常常用的数据结构,它允许我们以键-值(key-value)对的形式存储和访问数据。Python中的字典是无序的,意味着字典中的元素是没有固定顺序的。 字典提供了许多内置的方法来操作和处理数据。其中之一是max()方法,它允许我们找到字典中值最大的项。本文将详细介绍Python字典的max(...
在Python编程语言中,字典(Dictionary)是一种非常有用的数据结构,它允许我们存储和访问键-值对。字典是一种可变、无序的数据类型,可以通过键来快速查找对应的值。在Python中,字典使用大括号{}来表示,键值对之间使用冒号:分隔。在本文中,我们将探讨如何使用Python中的字典,并介绍一些与字典相关的常用方法和操作。 字典...

The largest string is: Python In the case of dictionaries,max()returns the largest key. Let's use thekeyparameter so that we can find the dictionary's key having the largest value. Example 3: max() in dictionaries square = {2:4,-3:9,-1:1,-2:4}# the largest key ...
fruits=["apple","banana","cherry","date"]longest_fruit=max(fruits,key=len)print(longest_fruit)# Output: "banana" 1.3. Find Max Key or Value in a Dictionary In this example, we are using themax()function to find the max key (lexicographically) and max value from adictionarytype. ...
In this guide, we'll take a look at how to find the maximum element of a few common data structures in Python, such as a list, dictionary, and tuple. The max() method, built into the Python namespace works wonders here for built-in types. How to Get the Max Element of a Python...
Here’s a summary of what the arguments to min() and max() do:ArgumentDescriptionRequired iterable Takes an iterable object, like a list, tuple, dictionary, or string Yes default Holds a value to return if the input iterable is empty No key Accepts a single-argument function to customize ...
Python基本数据类型总览: 1.Booleans(布尔型):其值为True或False 2.数值型,包含以下几种: integer(整数型) float(浮点型) fraction(分数) 复数 3.Strings(字符串) :元素不可修改 4.List(列表):有序可修改 5.Dictionary(字典):无序可修改的键值对 ...
