我只需要此文件中的“name”值。例如，在这个项目中它将是：
Taylor Kitsch, Lynn Collins, Samantha Morton, Willem Dafoe, Thomas Haden Church, Mark Strong, Ciar Hinds, Dominic West, James Purefoy, Bryan Cranston, Polly Walker等
使用键作为“名称”来表示值。
我应该怎么做呢？
答案 0 :(得分：2)
这样的事情应该有效。您可以使用csv库将行转换为数组以进行迭代。 ast库会将一个字符串转换为您可以键入的dict / json对象。
import ast
import csv
names = []
with open('csvFile.csv', 'r') as f:
reader = csv.reader(f)
for row in reader:
names.append(ast.literal_eval(row)[name])
# or you could print(name) here.
答案 1 :(得分：2)
您展示的是单个 JSON数组，而不是CSV。 （文件扩展名与Python无关）
从每个JSON数组行中的对象中解析名称
import json
with open("file.txt") as f:
for line in f:
names = (x['name'] for x in json.loads(line))
for name in names:
print(name)
答案 2 :(得分：0)
根据您提供的内容，这是一个非常基本的例子：
>>> movie = [{"cast_id": 5, "character": "John Carter", "credit_id": "52fe479ac3a36847f813ea75", "gender": 2, "id": 60900, "name": "Taylor Kitsch", "order": 0}, {"cast_id": 20, "character": "Dejah Thoris", "credit_id": "52fe479ac3a36847f813eab3", "gender": 1, "id": 21044, "name": "Lynn Collins", "order": 1}]
>>> for i in movie:
... print(i["name"])
...
Taylor Kitsch
Lynn Collins
基本上，这会迭代列表中的不同字典，然后提取与"name"键关联的值。
在整个csv文件中执行此操作需要更多信息，但这可能会让您入门。
答案 3 :(得分：0)
您可以直接使用过滤器发出请求
{'$filter': ['name eq Lynn Collins']}
答案 4 :(得分：-1)
