Accessing Column Headers from Pandas DataFrames
When working with user-defined Pandas DataFrames, the need arises to obtain a list of the column headers. This can be done in a straightforward manner using the DataFrame's built-in functionality.
Solution:
To retrieve a list of column headers from a Pandas DataFrame, you can employ the following methods:
Using the columns.values attribute:
<code class="python">column_list = list(my_dataframe.columns.values)</code>
Using the direct list conversion of the DataFrame:
<code class="python">column_list = list(my_dataframe)</code>
Both methods effectively provide a list of strings containing the column headers of the DataFrame. In the provided example, the resulting list for the given DataFrame would be ['y', 'gdp', 'cap'].
