如何在python中从csv中提取列

Question

我正在学习如何使用Python中的csv，我想阅读csv的第3列并打印出内容。我正在使用下面的代码，但运行时得到的输出为0

    with open('prospects.csv', 'r') as csv_file:
        pros = csv.reader(csv_file)
        for row in pros:
            print(row[2])

以下是CSV文件的一个片段：

Answer 1

如果你愿意使用熊猫（Pandas），那么

import pandas as pd
data = pd.read_csv('prospects.csv')

要获取“年龄”列，请使用

data['age']
