你可以使用Python的"Pandas"框架:

import pandas as pd

f = "路径/到/你的/文件.csv"
dataframe = pd.read_csv(f)
# 处理你的数据

Pandas为你提供了许多功能来处理和管理数据集。

或者你可以使用标准的CSV写入方法。

import csv

file = "路径/到/你的/文件.csv"
with open(file, "r") as f:
    reader = csv.reader(f)

    for row in reader:
    # 处理你的数据
英文:

You can use the python "Pandas" framework:

import pandas as pd

f = "path/to/your/file.csv"
dataframe = pd.read_csv(f)
# handle your data

Pandas gives you a lot of functionalities to handle and manage the dataset.

Or you can use the standard csv writer.

import csv

file = "path/to/your/file.csv"
with open(file, "r") as f:
    reader = csv.reader(f)

    for row in reader:
    # handle your data

尝试这个
```python
import csv
with open('myfile') as file:
    reader = csv.reader(file)
    for details in reader:
        #检索你的数据

我之前也需要做类似的事情,但涉及电子邮件和姓名。我有一个像这样的 csv 文件:
pic of csv file

然后我使用了这段代码

import csv
with open("emails.csv") as file:
    reader = csv.reader(file)
    next(reader)
    for name, email in reader:
        #在这里给每个人发送个性化的电子邮件

<details>
<summary>英文:</summary>

Try This
```python
import csv
with open(&#39;myfile&#39;) as file:
    reader = csv.reader(file)
    for details in reader:
        #retrieve your data

I had to do something similar before but with emails and names. I had a csv like this:
pic of csv file

Then I used this code

import csv
with open(&quot;emails.csv&quot;) as file:
    reader = csv.reader(file)
    next(reader)
    for name, email in reader:
        #sent each person a personalized email here
