In Python, you can use the pandas library to handle data and extract all values from a specific column in a data table. To start, use the read_csv function in the pandas library to read the CSV file containing the data.

import pandas as pd

# 读取CSV文件
data = pd.read_csv('data.csv')

# 获取某一列的所有值
column_values = data['column_name'].values

In this case, data.csv is the filename of the CSV file containing data, and column_name is the name of the column to be retrieved. Use the values attribute to retrieve all the values in that column, which will return a NumPy array containing all the values.
