How to get a value/row from pandas read_csv

Question

I am using a CSV file with news about crypto. My goal is to practice string manipulation and methods. The CSV looks something like this :

publishdate headlinetext

(...)

Then I used pandas to read the CSV.

import pandas as pd

news_headlines = pd.read_csv('/content/sample_data/crypto_headlines.csv')

news_headlines

Now I need to get the strings to work with them and change them to lower or upper case and then remove special characters.

However , I don't know which method I should use to extract a string from this variable I created called news_headlines.

Let's say I wanted to extract the 2nd row, with the publish date on 20130511.

Any help ?

Thanks in advance

您可以使用iloc() ，如下例所示，提取与第二行相关的字符串：

news_headlines.iloc[1, 1]
