解决方案:利用operator模块中的itemgetter()函数对这类结构进行排序是非常简单的。 # Sort a list of a dicts on a common key rows = [ {'fname': 'Brian', 'lname': 'Jones', 'uid': 1003}, {'fname': 'David', 'lname': 'Beazley', 'uid': 1002}, {'fname': 'John', 'lname': '...
将字典转换为 JSON 字符串,然后利用集合的唯一性来去重。 importjsondefremove_duplicates_dicts(list_of_dicts):seen=set()result=[]fordinlist_of_dicts:# 将字典转换为 JSON 字符串s=json.dumps(d,sort_keys=True)ifsnotinseen:seen.add(s)result.append(d)returnresult# 示例list_of_dicts=[{'name':'...
在Python中,我们可以通过使用列表推导式(List Comprehension)来将字典元素的值作为列表。 以下是一个示例代码: 代码语言:txt 复制 my_dict = {'name': 'Alice', 'age': 25, 'city': 'New York'} my_list = [value for value in my_dict.values()] print(my_list) ...
y.sort(reverse=True) printy#[8, 3, 2, 1, 0] list的reverse()函数 方法没有返回值,但是会对列表的元素进行反向排序。 aList=[123,'xyz','zara','abc','xyz'];aList.reverse();print"List : ",aList; python交换两个值 可以多个变量同时交换 复制代码代码如下: a=50 b=10 c=20 c,b,a =...
