Python读取csv文件

Posted 2021-03-19 MilesMa

创建一个csv文件，命名为data.csv，文本内容如下：

root,123456,login successfully
root,wrong,wrong password
wrong,123456,nonexistent username
,123456,username is null
root,,password is null

使用Excel打开如图：

利用Python内置的csv读取内容：

import csv

with open(\'data.csv\', \'r\', encoding=\'utf-8\')as f:

    reader = csv.reader(f)

    for i in reader:
        print(i)

输出结果：

[\'root\', \'123456\', \'login successfully\']
[\'root\', \'wrong\', \'wrong password\']
[\'wrong\', \'123456\', \'nonexistent username\']
[\'\', \'123456\', \'username is null\']
[\'root\', \'\', \'password is null\']
