Get a list from Pandas DataFrame column headers

Get a list from Pandas DataFrame column headers

You can get a list of column headers from a Pandas DataFrame by accessing the columns attribute of the DataFrame. Here's how you can do it:

import pandas as pd # Create a sample DataFrame data = {'Name': ['Alice', 'Bob', 'Charlie'], 'Age': [25, 30, 35], 'City': ['New York', 'San Francisco', 'Los Angeles']} df = pd.DataFrame(data) # Get a list of column headers column_headers = df.columns.tolist() print(column_headers)

In this example, we first import the Pandas library, create a sample DataFrame called df, and then use the columns attribute to get the column headers as a list using tolist(). The column_headers variable will contain a list of the column names from the DataFrame.
