如何访问具有多个字典的列表中类似的键、值对

Question

假设我有下面的清单

[{
    "user_id": 1,
    "firstname": "James",
    "lastname": "Katarikawe",
    "email": "jpkatarikawe@gmail.com",
    "password": "$3cur!ty1"
},
    {
    "user_id": 2,
    "firstname": "Paul",
    "lastname": "Kayongo",
    "email": "nserekopaul@gmail.com",
    "password": "rasengan"
}]

如何仅打印列表中所有项目的电子邮件和密码值

Answer 1

for d in entry_list:
    print(d["email"])
    print(d["password"])

Answer 2

for element in mylist:
    print(element['email'])
    print(element['password'])

说明：

使用变量迭代list

for element in mylist:

打印所需值：

print(element['email'])
print(element['password'])

Answer 3

l = [{
    "user_id": 1,
    "firstname": "James",
    "lastname": "Katarikawe",
    "email": "jpkatarikawe@gmail.com",
    "password": "$3cur!ty1"
},
    {
    "user_id": 2,
    "firstname": "Paul",
    "lastname": "Kayongo",
    "email": "nserekopaul@gmail.com",
    "password": "rasengan"
}]
for item in l:
    print(item['email'], item['password'])
