print(key, ':', value) test(Ruby=277, MySQL=288, Java=299) 1. 2. 3. 4. 5. 和上面一样,如果传入的是字典也需要使用**解包 def test(**a): for key, value in a.items(): print(key, ':', value) language = {'C++':277, 'C#':288, 'Java':299, 'Python':311} test(**langua...
key1=value1&key2=value2&key2=value3,其中key2对应的值有2个value2和value3。 那么在传值的时候,可以把多个值放到一个list,如 代码语言:javascript 代码运行次数:0 运行 AI代码解释 params={'key1':'value1','key2':['value2','value3']} 也可以使用列表嵌套元祖 代码语言:javascript 代码运行次数:0...
1.深度复制字典:deepcopy方法,必须利用copy库,这个结果只有数据,内部没有指针了。 2.如果只要赋值第一层的数据,只需采用字典自带的copy方法。 本节视频教程 一、初始化字典 我们以前对空字典的初始化是这样的,空字典的初始化:dic1={} 我们想要初始化有数据的字典的方式:dic1={"a":"老刘","b":"老王头",...
# v = "k1" in dic # print(v) # v = "v1" in dic.values() # print(v) #六、布尔值 # 0 1 # bool(...) # None "" () [] {} 0 ==> False ### # list # 类,列表 # li = [1, 12, 9, "age", ["石振文", ["19", 10], "庞麦郎"], "alex", True] # 通过list...
接着通过playwright分别发送GET和POST请求,参数均为:{"key1": "value1", "key2": "value2"},并实现如下功能: 1、将GET请求的key1的值修改为“GET”; 2、将POST请求的key1的值修改为“POST”。 首先需要一个方法处理GET/POST的参数,将key1的值做修改: ...
data=response.json()value=data["key"]print(value) 1. 2. 3. 4. 5. 6. 上述代码中,我们使用data["key"]的方式来访问字典中的值,并将其赋值给变量value。 遍历字典中的键值对: importrequests response=requests.get(" data=response.json()forkey,valueindata.items():print(key,value) ...
my_list = [123, 'qwe', {'key': 'value'}] print(my_list) # [123, 'qwe', {'key': 'value'}] As you can see from the above example, the list contains different types of data. How to get the length of the list? To get the length of a Python list, you can use the len(...
