Python 导入 csv 到列表 [英] Python import csv to list

问题描述

我有一个包含大约 2000 条记录的 CSV 文件.

I have a CSV file with about 2000 records.

每条记录都有一个字符串和一个类别:

Each record has a string, and a category to it:

This is the first line,Line1
This is the second line,Line2
This is the third line,Line3

我需要将此文件读入如下所示的列表:

I need to read this file into a list that looks like this:

data = [('This is the first line', 'Line1'),
        ('This is the second line', 'Line2'),
        ('This is the third line', 'Line3')]

如何使用 Python 将此 CSV 导入到我需要的列表中?

How can import this CSV to the list I need using Python?

推荐答案

使用 csv 模块:

import csv

with open('file.csv', newline='') as f:
    reader = csv.reader(f)
    data = list(reader)

print(data)

输出:

[['This is the first line', 'Line1'], ['This is the second line', 'Line2'], ['This is the third line', 'Line3']]

如果你需要元组:

If you need tuples:

import csv

with open('file.csv', newline='') as f:
    reader = csv.reader(f)
    data = [tuple(row) for row in reader]

print(data)

输出:

[('This is the first line', 'Line1'), ('This is the second line', 'Line2'), ('This is the third line', 'Line3')]

Old Python 2 答案，也使用 csv 模块:

import csv
with open('file.csv', 'rb') as f:
    reader = csv.reader(f)
    your_list = list(reader)

print your_list
# [['This is the first line', 'Line1'],
#  ['This is the second line', 'Line2'],
#  ['This is the third line', 'Line3']]
