Python将csv导入到包含多行的列表中

Question

我想导入包含4个值的database.csv

key,email1,email2,email3
filename,email@example.com,email2@example.com,email3@example.com
filename2,email@yahoo.com,email@google.com,email@outlook.com
etc,etc,etc,etc

接下来我想将列密钥分隔为等于文件名列表，将email1，email2和email3分隔为另一个列表

key = [filename]
emails = [email@example.com,email2@example.com,email3@example.com]

当前代码

import csv
with open('data.csv') as read_csv:
reader = csv.reader(read_csv)
for row in reader:
    key = row[0]
    emails = row[1::]
return key
return emails

输出

key = [filename2]
emails = [filename2,email@yahoo.com,email@google.com,email@outlook.com]

我需要的是与电子邮件相对应的密钥以传递给另一个函数。

Answer 1

字典听起来像是适当的解决方案。

import csv
result = {}
with open('data.csv') as read_csv:
    reader = csv.reader(read_csv)
    for row in reader:
        result[row[0]] = row[1:]

然后，您可以随时访问或传递如下值：

result[filename2]
