在列表中编辑词典很简单。你知道吗

首先，您需要通过调用字典所在列表的索引来获取字典。你知道吗

然后你可以像平常一样编辑字典。你知道吗

看看下面的例子。 我已经写了几个循环来阅读或编辑列表中的词典。你知道吗

list_of_dicts = [{"name":"Mike","age":30}, {"name":"Dave","age":22}, {"name":"Amber","age":24}]


for ndex, item in enumerate(list_of_dicts):
    # This will print the index number and dictionary at that index.
    print(ndex, item)


for item in list_of_dicts:
    # This will print each persons name and age of each dict in the list.
    print("The persons name is {} and they are {} years old!".format(item["name"], item["age"]))


for item in list_of_dicts:
    # this will update the age of each person by 1 year.
    item["age"] += 1
print(list_of_dicts)


# This will change Daves name to Mark.
list_of_dicts[1]["name"] = "Mark"
print(list_of_dicts[1])

如果运行上述脚本，则应在控制台中获得以下结果：

0 {'name': 'Mike', 'age': 30}
1 {'name': 'Dave', 'age': 22}
2 {'name': 'Amber', 'age': 24}
The persons name is Mike and they are 30 years old!
The persons name is Dave and they are 22 years old!
The persons name is Amber and they are 24 years old!
[{'name': 'Mike', 'age': 31}, {'name': 'Dave', 'age': 23}, {'name': 'Amber', 'age': 25}]
{'name': 'Mark', 'age': 23}
