# Define a function 'sort_dict_by_value' that takes a dictionary 'd' and an optional 'reverse' flag.# It returns the dictionary sorted by values in ascending or descending order, based on the 'reverse' flag.defsort_dict_by_value(d,reverse=False):returndict(sorted(d.items(),key=lambda...
dictionary.sort(key=lambda x: x[1], reverse=True) 其中,key参数指定一个函数,用于从字典条目中提取比较值。reverse参数设置为True表示按降序排列,即从大到小排列。例如,上述代码演示了如何使用sort方法对字典按照值的大小进行降序排列: fruits = ['apple': 3, 'banana': 2, 'orange': 5] fruits.sort(ke...

By: Rajesh P.S.To sort a dictionary by its values in Python, you can use the sorted() function along with a lambda function as the key argument. The lambda function is used to extract the values from the dictionary, and sorted() returns a new list of tuples containing the key-value...
You can sort a dictionary by its keys using sorted() with .items() and dict(). To sort by values, you use sorted() with a key function like lambda or itemgetter(). Sorting in descending order is possible by setting reverse=True in sorted(). For non-comparable keys or values, you ...
